Common GPA Explanation Pitfalls in TMDSAS and How to Avoid Them

The fastest way to raise red flags in a Texas medical school application is to mishandle your TMDSAS GPA explanation.

Most applicants worry about the GPA itself. Committees in Texas often worry more about how you explain it. A 3.2 with a mature, precise explanation harms you far less than a 3.6 paired with a defensive, vague, or blame-heavy narrative.

You cannot fix your GPA in TMDSAS. You can make it look significantly worse by explaining it poorly.

This is where applicants sabotage themselves.

Below are the most common GPA explanation pitfalls in TMDSAS—and how to avoid turning a required text box into an invitation for rejection.

Mistake #1: Writing When You Should Stay Silent

The first and most damaging mistake: explaining a GPA that does not need an explanation.

TMDSAS gives you multiple places where you can comment on academics:

• “Explanation Statement” (the classic catch-all)
• Optional essays / additional essays some schools read closely
• Institutional Explanation (if applicable)

Many premeds treat these as compulsory confessionals. They are not.

When a GPA Explanation Is Not Necessary

You usually do not need a GPA explanation if:

• Your overall GPA is ≥ 3.6 and BCPM ≥ 3.5 with no major term anomalies
• Your GPA is stable or shows a mild upward trend
• You have one or two B–/C+ grades scattered across several semesters
• You had a single difficult course (e.g., Organic Chemistry I C+) with no pattern of struggle

For Texas schools, a 3.5 with one “off” semester still looks solid if the rest of the record supports it. Calling attention to minor, normal variation makes committees ask: “What are we supposed to be worried about here?”

You do not want that question.

When a GPA Explanation Is Justified

You should strongly consider a concise explanation if:

• You have a significant downward trend (e.g., multiple low semesters late in college)
• You had one or more semesters below ~3.0
• You withdrew from a full course load (W’s across the board) in a term
• There is an obvious before/after pattern tied to a clear event (illness, family crisis, work burden)
• Post-bacc or graduate GPA is drastically different from undergraduate performance

Even then, the standard is high: if you cannot explain it clearly in a short, factual way that ends in demonstrated recovery or improvement, you risk making things worse.

Mistake to avoid: Treating the GPA explanation box like required therapy. If you are stretching to justify something committees might not even see as a problem, you are likely over-explaining.

Mistake #2: Turning the Explanation into Excuse-Making

Adcoms are not allergic to explanations. They are allergic to excuses.

There is a difference between:

• “I had mono during spring 2022 which led to several absences and two incomplete courses. Once recovered, I repeated the coursework and returned to my prior level of performance.”
  and
• “My grades dropped because multiple professors were unfair and my roommate was loud so I could not study.”

Texas schools see thousands of applications. They know what real life looks like. They also know when someone is avoiding accountability.

Red-Flag Excuse Patterns

Avoid explanations that:

• Blame professors (“The grading was harsh”; “The professor did not teach well”)
• Blame classmates (“My lab partners did not pull their weight”)
• Blame abstract difficulty (“The material was unusually hard”)
• Insist “I am really a good student” without evidence
• Describe “stress” in very general terms with no specific event, treatment, or resolution

A statement like:

“I was very stressed that year and my grades suffered.”

tells the reader nothing actionable. It suggests you crumble when life gets tough—exactly the opposite of what medical schools want.

The Accountability Standard

A stronger pattern looks like:

• Brief context
• Your role and responsibility
• Specific steps you took to address it
• Evidence of improved performance afterward

For example:

“During my sophomore fall, I underestimated the time required for Organic Chemistry I and Physics I while holding two part-time jobs. I overextended myself and earned a C+ and B– respectively. In subsequent terms, I reduced my work hours, used structured study schedules, and sought tutoring early. My grades in upper-level sciences (e.g., Biochemistry A, Physiology A–) reflect these changes.”

No drama. No blaming. Clear ownership and improvement.

Mistake to avoid: Using the GPA box to justify yourself instead of to demonstrate maturity and problem-solving.

Mistake #3: Writing a Life Story Instead of a Focused Explanation

TMDSAS does not want a memoir. They want an academic explanation.

Many applicants commit a fatal error: they merge their childhood trauma, family history, career motivations, and every adversity they ever experienced into one sprawling GPA explanation paragraph.

That is what the personal statement, secondary essays, and optional adversity essays are for.

Signs You Are Oversharing in the Wrong Place

You are likely overdoing it if:

• Your GPA explanation is longer than multiple paragraphs
• You repeat stories already detailed in your personal statement
• You re-argue your entire premed journey
• You describe unrelated events that did not directly affect academic performance

For example, this is too broad:

“Growing up in a low-income household, I always had to work. In high school I balanced multiple responsibilities and that continued into college. My immigrant background, family obligations, and desire to help my siblings shaped my resilience…”

That may all be true and important—but it belongs somewhere else in the application. In a GPA explanation, adcoms want one question answered: what specifically explains the pattern we see in your grades?

Keep the Scope Tight

Structure your explanation around what changed in your academic environment or capacity:

• Health event (illness, surgery, mental health crisis with treatment)
• Major family event (death, caregiving responsibilities with clear timeline)
• Work hours that substantially limited study time
• Transition adjustment (e.g., first-gen student struggling first term, then adapting)
• Incorrect time management / over-commitment with clear correction

Everything else dilutes the message and tests the reader’s patience.

Mistake to avoid: Treating the GPA section as your only chance to be understood. It is not. It is a narrow, targeted tool.

Mistake #4: Failing to Show Recovery or Change

A weak explanation describes the problem. A strong one proves you are no longer that problem.

Many applicants say:

• “My grades dipped because my grandmother died.”
  or
• “I struggled with depression which affected my performance.”

They stop there. This is dangerous.

Committees are asking:

• Are these circumstances still ongoing?
• Has the applicant developed coping strategies?
• What evidence shows they can handle medical school rigor now?

Always Include a Resolution

You must answer, explicitly or implicitly: Why should we trust your future performance?

Good explanations end with:

• A clear change (reduced work hours, changed major, new study habits, medical treatment)
• A timeline (when the issue resolved or became controlled)
• Objective data that supports improvement (GPA trend, MCAT, post-bacc grades)

For instance:

“During fall 2020 I experienced untreated depression that interfered with concentration and attendance, resulting in a 2.6 term GPA. I sought care with a campus counselor and my physician, began treatment, and developed structured study routines. Since spring 2021, I have maintained term GPAs above 3.7 in full science course loads, which more accurately reflect my current abilities.”

That last sentence matters more than the description of the problem. Texas schools are risk-averse about academic failure; they want proof, not promises.

Mistake to avoid: Describing hardship without demonstrating that it is now managed, resolved, or effectively accommodated.

Mistake #5: Over-medicalizing or Under-medicalizing Health Issues

Health-related GPA explanations are landmines. Handle them poorly and you either:

• Sound vague and non-credible (“health issues affected my performance”), or
• Raise concerns about your stability or future capacity without reassuring evidence.

The Overly Vague Health Explanation

Lines like:

• “I had personal medical challenges that impacted my grades.”
• “Health complications disrupted my semester.”

are essentially redacted statements. Committees cannot assess severity, duration, or resolution; they are left guessing, which rarely favors you.

The Overly Detailed Health Disclosure

On the other end, some applicants:

• List diagnoses and medications
• Share graphic details about hospitalizations
• Describe current symptoms that sound uncontrolled

This invites the question: Will this condition jeopardize their ability to handle medical school? If the answer is not clearly “no” based on your description, you have created an avoidable concern.

The Balanced Approach

Aim for:

• General but meaningful description (e.g., “treated anxiety disorder,” “autoimmune flare requiring surgery,” “concussion with prolonged recovery”)
• Clear timeline
• Explicit current status (stable, well-managed, effective treatment, no recent episodes)
• Evidence that your recent performance is strong and sustained

Example:

“In spring 2019, I experienced an anxiety disorder that led to significant sleep disruption and poor concentration. I began treatment with a therapist and physician that semester. Since then, my symptoms have been well-controlled, and I have maintained full course loads with term GPAs of 3.7 or higher for the past four semesters.”

You do not need to name specific medications or intimate details. Focus on function and stability.

Mistake to avoid: Either hiding behind vague “health issues” or oversharing raw medical detail without emphasizing current control and academic resilience.

Mistake #6: Ignoring the Texas Context and TMDSAS Structure

TMDSAS schools are not AMCAS schools with different branding. They have their own culture and expectations.

Underestimating How Data-Rich TMDSAS Is

TMDSAS provides:

• Detailed term-by-term GPAs
• Separate BCPM (science) and overall GPAs
• Undergraduate vs. post-bacc vs. graduate breakdowns

Committees will see patterns like:

• Steep dip during junior fall
• Significant upward trend after a post-bacc or SMP
• Strong MCAT contrasting with weak freshman year

Your explanation must align with obvious patterns in this data structure.

For example, claiming “I struggled early in college but improved steadily” when TMDSAS shows:

• Freshman: 3.6
• Sophomore: 3.4
• Junior: 2.9
• Senior: 3.1

will not fly. The reader sees the opposite. You must be precise:

“My performance declined during junior year due to X. After addressing Y, my senior-year trend and post-bacc work show…”

Not Using TMDSAS Categories to Your Advantage

Texas schools often care about:

• Evidence you can handle recent hard science
• Texas residency context (commuting, work, family obligations)
• Non-traditional paths (career change, military, family responsibilities)

If you are a non-traditional applicant with early poor grades from 8–10 years ago and recent strong TMDSAS-posted work, your explanation should:

• Briefly note immaturity or lack of direction then
• Emphasize sustained recent excellence in relevant coursework

For example:

“My earliest undergraduate work (2009–2011) reflects poor judgment about priorities and a lack of academic direction. Since returning to school in 2020 with a clear goal of medicine, I have completed 45+ hours of upper-division sciences with a 3.85 GPA. This recent performance is a more accurate indicator of my current readiness.”

Mistake to avoid: Writing generic explanations that ignore how TMDSAS displays your academic record and what Texas committees actually weigh heavily.

Mistake #7: Poor Tone, Grammar, and Professionalism

Content is not the only risk. Sloppy execution in the GPA explanation can raise serious doubts about your communication skills and judgment.

Tone Problems

Common tone errors:

• Overly emotional or dramatic (“I was devastated, broken, and hopeless…”)
• Aggressive or bitter (“Despite my professor’s unfair grading policies…”)
• Overly casual (“Stuff just piled up and I kinda shut down…”)

Professional tone does not mean cold. It means controlled.

Aim for:

• Calm, factual description
• Limited emotional language
• Focus on actions taken and lessons learned

You are not trying to make the reader feel sorry for you. You are trying to earn their respect.

Writing Quality Issues

The explanation section is short; errors are magnified:

• Grammar mistakes
• Typos
• Run-on sentences
• Confusing timelines

If you cannot write 3–8 clean sentences about your own history, reviewers worry about your ability to document patient care notes, communicate with teams, or handle exams that require precise reading.

Have at least one critical reader (not just a friend who says “looks fine”) review your explanation for clarity and tone. Premed advisors and writing centers often miss the nuance; someone familiar with medical admissions or at least graduate-level applications is better.

Mistake to avoid: Treating the explanation as a quick afterthought because it is “just a small box.” That small box can outweigh a hundred strong shadowing hours if handled carelessly.

---

Mistake #8: Contradicting the Rest of Your Application

The final, subtle danger: misalignment.

Your GPA explanation must harmonize with:

• Your personal statement
• Your activities descriptions
• Any TMDSAS “optional” essays you choose to submit
• Letters of evaluation (if they reference hardships or patterns)

Common Contradictions

1. Workload mismatch

   • Explanation: “I had to work 30 hours per week, affecting my grades.”
   • Activities: show 5–8 hours per week of work during that time.
     The committee will notice.

2. Timeline mismatch

   • Explanation: “My mother’s illness during my junior year led to my lower grades.”
   • Transcript: junior year shows 3.8; senior year shows 2.9.

3. Personality mismatch

   • Personal statement: highly reflective, taking ownership.
   • GPA explanation: blame-heavy and defensive.

When in doubt, pull your transcript, activity list, and essays together and review them as one story. Ask: Would a stranger find this coherent?

Mistake to avoid: Writing the GPA explanation in isolation, without checking it against dates, activities, and themes already in your TMDSAS application.

How to Build a Strong, Risk-Minimizing GPA Explanation

To avoid these pitfalls, use a simple framework. Think of it as damage control by design.

Step 1: Decide If You Truly Need One

Ask yourself:

• Is there a clear anomaly or pattern an adcom will immediately see?
• Is there a specific, bounded cause that directly affected academics?
• Do I have evidence of improvement or stability after the event?

If you cannot answer “yes” to at least two of those, you may not need (or benefit from) an explanation.

Step 2: Draft with Four Anchors

Keep it to roughly 3–8 sentences built around:

1. Context – What happened, when, and how it related to school.
2. Impact – How this specifically affected your coursework.
3. Response – What you did to address it (behavioral, structural, medical, etc.).
4. Outcome – How your grades and functioning look since then.

Example structure:

“During [timeframe], [brief context] led to [specific impact on academics]. Recognizing this, I [actions taken / changes made]. As a result, since [timepoint], I have [objective evidence of improvement].”

Step 3: Strip Out Red Flags

Revise to remove:

• Blame on others
• Emotional overload
• Unnecessary medical detail
• Long narratives better suited for other essays

Keep what remains:

• Specific
• Honest
• Focused on responsibility and growth

Brief Takeaways

1. Do not explain what does not need explaining; unnecessary GPA narratives invite scrutiny you do not want.
2. When an explanation is warranted, keep it concise, factual, accountable, and resolution-focused—no excuses, no drama.
3. Ensure your TMDSAS GPA explanation aligns with the rest of your application and clearly demonstrates that past problems are solved, not ongoing.
