Physics is about 36 of the 180 MDCAT questions. A fifth of the paper. It is also the subject most students decide early on that they are bad at, which turns into a decision to lose 36 marks before the paper has even been set.
Here is the thing worth knowing: MDCAT physics is not FSc physics with harder algebra. It is one-minute questions. Nobody is asking you to derive anything.
You need fewer formulas than you think
Build one sheet, in your own handwriting, with every formula you are likely to need, grouped by topic: motion and force, work and energy, circular motion, waves and sound, thermodynamics, electrostatics, current electricity, electromagnetism, and modern and nuclear physics.
Keep it to a sheet. If it runs to four pages you are copying the book rather than selecting from it. Then read it daily, properly, for two minutes. Daily recall is what moves a formula from "I have seen that" to "I have it", and in an MCQ exam that difference is worth more than any amount of derivation practice.
Read the question before you reach for a formula
Most physics marks in this exam are lost in the first fifteen seconds, not the last. Three habits fix that:
- Check what is actually being asked. Speed or velocity. Distance or displacement. Power or energy. The wrong one is always an option.
- Check the units given and the units wanted. A quantity in centimetres and an answer in metres is the most common trap in the whole subject.
- Notice what is being held constant. Half of thermodynamics and gas questions are decided by that one word in the stem.
You rarely need to finish the algebra
In a four-option question, finishing the calculation is often the slow way round.
- Use dimensions. Work out what units the answer must be in, and most of the time two options disappear immediately.
- Estimate. Round hard, get the order of magnitude, and see which option is in the right territory. Exam numbers are usually far enough apart for this to work.
- Check the extremes. Ask what happens if the quantity goes to zero, or gets very large. An option that behaves wrongly at the extreme is wrong everywhere.
- Know the standard values. Gravity, the speed of light, the charge on an electron. Reaching for them should cost no thought.
These are not tricks for weak students. They are how you buy back the seconds you will need for the Biology section.
The topics that keep coming back
Across past papers, some areas repeat. Give them the first share of your time:
- Motion, force and Newton's laws, including projectiles.
- Work, energy and power, and conservation arguments.
- Circular motion and gravitation.
- Waves and sound, with the Doppler effect.
- Thermodynamics, the laws and their sign conventions.
- Electrostatics and current electricity, including simple circuits.
- Electromagnetism, and the direction rules you must not mix up.
- Modern and nuclear physics, which is largely recall and often the easiest set of marks in the paper.
You can see how physics sits against the other subjects in the full syllabus, and work through it topic by topic in MDCAT Physics practice.
Practise against the clock, early
One minute per question is the real constraint, and an untimed physics question tells you almost nothing about how you will do. Time yourself from the beginning, even on a set of ten.
When you get one wrong, decide which it was: a formula you did not have, a question you misread, or arithmetic you fumbled. Three different problems, three different fixes. Students who sort their mistakes this way improve far faster than students who simply do more questions.
Thirty-six marks is the difference between a merit list you make and one you miss. That is too much to hand over because physics felt hard in Part One.
