Biophysics PASS / LAS (Pre-Med) Revision Sheets
PASS UE3 applies physics to living phenomena: states of matter, fluid flow, waves, radiation and medical imaging. It's a technical UE that rewards formula mastery and calculation drilling.
Biophysics curriculum in PASS / LAS (Pre-Med)
The curriculum covers states of matter (gases, liquids, solids), thermodynamics, fluid mechanics (Bernoulli, Poiseuille for blood circulation), waves (acoustics, ultrasound, echography), geometric optics (eye, microscope), ionizing radiation (radioactivity, dosimetry) and medical imaging (X-rays, CT, MRI, nuclear medicine).

Tips to succeed in biophysics PASS / LAS (Pre-Med)
Build a single sheet with all formulas and SI units next to each variable: 80% of exam mistakes come from unit errors
Practice calculations without a calculator (if allowed): mental-math speed makes the difference in timed MCQs
Understand the physics behind each imaging modality (X-ray, MRI, ultrasound) instead of rote memorizing: the question pattern is the same each year
For numerical problems, anticipate orders of magnitude before calculating: it protects against decimal-point traps
FAQ — Biophysics PASS / LAS (Pre-Med)
Is biophysics really make-or-break in PASS?
Biophysics isn't officially eliminatory but its coefficient and technical difficulty often create score gaps. Students who neglect it commonly lose 4-6 points, placing them below the cutoff. Regular work (3-4 hours/week) is enough to score decently without spending disproportionate time on it.
How do I memorize biophysics formulas in PASS?
Rather than rote memorizing, understand each formula's derivation: Poiseuille follows from a force balance, Bernoulli from energy conservation. Build FSRS flashcards with the formula on the front and the application context on the back. Do 5-10 exercises per chapter — memorization comes from use, not passive reading.
Which calculator should I use for PASS biophysics?
Most faculties forbid calculators in the PASS concours: MCQs are calibrated to be solved by hand or mentally. From the start, get used to calculating without a calculator: approximations, orders of magnitude, algebraic simplifications. A few faculties allow a basic (non-graphing) calculator — check your university's rules.
