The MDCAT has undergone three major structural changes in as many years — from PMC's 210-MCQ computer-based test, to PM&DC's 200-MCQ paper-based format in 2024, to the newest version with 180 MCQs and a significantly heavier Biology weightage. If you are preparing for MDCAT 2026, you need to know exactly which version you are preparing for and what changed.
This guide gives you everything: a side-by-side comparison of all three versions, the complete official topic list for every subject, high-priority areas based on MCQ count, and a strategy section to help you allocate your preparation time correctly.

1. All Three MDCAT Versions Compared
Three different regulatory bodies have defined the MDCAT in recent years. Here is every structural difference, side by side:
| Feature | PMC (Old) ~2020–2023 |
PM&DC 2024 2024 |
New Version 2025/2026 |
|---|---|---|---|
| Total MCQs | 210 | 200 | 180 |
| Duration | 3.5 hours | ~3 hours | 3 hours |
| Format | Computer-based | Paper-based | Paper-based |
| Negative Marking | No | No | No |
| Biology | 68 MCQs / 32% | 68 MCQs / 34% | 81 MCQs / 45% ↑ |
| Chemistry | 56 MCQs / 26.5% | 54 MCQs / 27% | 45 MCQs / 25% ↓ |
| Physics | 56 MCQs / 26.5% | 54 MCQs / 27% | 36 MCQs / 20% ↓ |
| English | 20 MCQs / 10% | 18 MCQs / 9% | 9 MCQs / 5% ↓ |
| Logical Reasoning | 10 MCQs / 5% | 6 MCQs / 3% | 9 MCQs / 5% |
| Pass Marks — Medical | 65% | 65% | 55% ↓ |
| Pass Marks — Dental | 65% | 55% | 50% |
The most important change for 2026 is the Biology weight jumping from 32–34% to 45%. This means Biology alone carries nearly half your total score. If you were preparing using old PMC ratios, you need to rebalance your study schedule immediately — giving Biology roughly 2× the time you give Physics.

6. English — 9 MCQs (5%)
English drops sharply from 20 MCQs (PMC) to just 9 in 2026 — the smallest allocation. This makes English a "secure the easy marks" section rather than a score differentiator. The 6 official skill areas are:
| # | Skill Area | What to Expect |
|---|---|---|
| 1 | Vocabulary | Meaning from context · Synonyms & antonyms · Homophones · Word relationships · Morphology |
| 2 | Tenses & Sentence Structure | All present & past tenses · Four sentence types · Conditionals · Types of clauses · Sentence fragments |
| 3 | Grammar & Writing Conventions | Correct vs incorrect sentence structure · Capitalization & punctuation (semicolons, commas, apostrophes, abbreviations) |
| 4 | Subject-Verb Agreement & Prepositions | Correct subject-verb agreement · Appropriate use of articles (a, an, the) · Correct use of prepositions in context |
| 5 | Error Identification | Identifying errors of word order, style, vocabulary in sentences |
| 6 | Reading Comprehension | Short passage comprehension · Text-explicit questions · Selecting most appropriate responses |
7. Logical Reasoning — 9 MCQs (5%)
Logical Reasoning is back to 9 MCQs (5%) after being reduced to just 6 in PM&DC 2024. These questions require no factual knowledge — only analytical thinking. The 6 question types are:
| # | Type | Description |
|---|---|---|
| 1 | Critical Thinking | Evaluate statements as True, Probably True, Insufficient Data, Probably False, or False based on a short passage |
| 2 | Letter & Symbol Series | Find the pattern in sequences of letters, numbers, or symbols and predict the next element |
| 3 | Logical Deduction | Use structured reasoning to deduce conclusions from a set of given statements |
| 4 | Logical Problems | Deductive reasoning puzzles — use pieces of information to arrive at a specific answer |
| 5 | Course of Action | Given a problem statement, determine which suggested action(s) logically follow |
| 6 | Cause & Effect | Identify cause-and-effect relationships between two given statements |
Logical Reasoning is the highest return-on-investment section: 9 marks, zero memorization required. Practice 20–30 sample questions in the week before the exam. Focus especially on critical thinking and logical deduction types, which appear most frequently.
8. Difficulty Levels Compared Across All Three Versions
| Difficulty Level | PMC | PM&DC 2024 | New 2025/2026 |
|---|---|---|---|
| Easy | 20% | — | 15% |
| Moderate | 60% | — | 70% |
| Difficult/Hard | 20% | — | 15% |
| Recall vs Application (Bio/Chem/Phys) | 70% recall · 30% application | — | 70% moderate (implies application) |
The shift to 70% moderate questions means fewer purely definitional recall questions and more application-style MCQs. Preparing by memorizing definitions alone will not be sufficient — you need to practice applying concepts to scenarios, especially in Bioenergetics, Chemical Equilibrium, and Force & Motion.
9. Preparation Strategy for MDCAT 2026
Given the 2026 structure, here is how to allocate your preparation time:
| Subject | MCQs | % of Score | Recommended Study Allocation |
|---|---|---|---|

Is MDCAT 2026 paper-based or computer-based?
MDCAT 2026 is paper-based (pen and paper MCQs). This continues the format introduced by PM&DC in 2024, replacing the computer-based PMC test.
What changed from PMC to the new 2026 MDCAT?
Three major changes: (1) Total MCQs reduced from 210 to 180. (2) Format changed from computer-based to paper-based. (3) Biology weight jumped from 32% to 45%, while Chemistry dropped from 26.5% to 25%, Physics from 26.5% to 20%, and English from 10% to 5%. Passing marks also decreased from 65% to 55% for Medical.
Which subject has the most MCQs in MDCAT 2026?
Biology has 81 MCQs (45%) — nearly half the total test. This is a massive increase from the PMC era (68 MCQs / 32%). Students should prioritize Biology above all other subjects in their MDCAT 2026 preparation.
Is there negative marking in MDCAT 2026?
No. There is no negative marking in MDCAT 2026 — same as all previous versions (PMC and PM&DC). Attempt every question, even if uncertain.
