MDCAT 2012
219 questions, every answer verified. Free to try.
ℹ️ 219 of 220 questions available; Q148 was voided in UHS's own key. Option letters match the printed paper. Where the old key contradicts clear science the correct answer is used and explained.
When the official key is wrong, we say so.
Every answer here is checked against the official key published for that paper. Where the key and the subject disagree — and on some papers that happens dozens of times — we mark the answer the science supports, and the explanation on that question says plainly that we have departed from the key and why. One paper's published key turned out to belong to a different paper code entirely.
Where a question cannot be resolved at all — an unreadable scan, a missing diagram, an option the original paper never printed — we switch it off rather than guess, and the paper's own note tells you how many are missing and which. That is why a paper can read 218 of 220 instead of a tidy 100%: the number is the truth about the paper, not a target.

- Q1 · MDCAT 2012 · Electromagnetism
A 10 cm long solenoid has 100 turns. What will be the magnetic field inside it along its axis if one micro ampere current is passed through it?
- A.4π × 10⁻¹³ tesla
- B.4π × 10⁻⁷ tesla
- C.4π × 10⁻¹⁰ tesla
- D.4π × 10⁻¹⁶ tesla
Show answer
Answer: C. 4π × 10⁻¹⁰ tesla — B = μ₀nI = 4π×10⁻⁷ × 1000 × 10⁻⁶ = 4π×10⁻¹⁰ T.
- Q2 · MDCAT 2012 · Carboxylic Acids
In the reaction CH₃COOH + PCl₅ → CH₃COCl + POCl₃ + HCl, the nucleophile which attacks on the carbon atom of acid is:
- A.OH⁻
- B.P
- C.Cl⁻
- D.H⁻
Show answer
Answer: C. Cl⁻ — Cl⁻ (released from PCl5) is the nucleophile that attacks the carbonyl carbon.
