Subject-Specific (Physics, Chemistry or Biology)
The subject-specific section matches your programme group: you answer Physics, Chemistry, or Biology. It rewards correct definitions, units, and formula application rather than broad reading. Study your own group’s core topics.
What is tested
- Physics: mechanics (Newton’s laws, work-energy, momentum), waves, electricity (Ohm’s law, series/parallel circuits), and basic modern physics. Direction and units matter.
- Chemistry: atomic structure, periodic trends, bonding, stoichiometry, acids and bases, and organic functional groups.
- Biology: cell structure, transport across membranes, enzymes, genetics, and human physiology such as circulation, respiration, and digestion.
Worked example (Physics)
A 2 kg block starts from rest and is pulled 5 m by a constant 10 N force on a frictionless surface. Find its final speed. Work done = Fd = 10×5 = 50 J. This equals the change in kinetic energy: ½mv² = 50. So v² = 2×50/2 = 50, and v = √50 ≈ 7.1 m/s. The reasoning is work-energy, not F=ma alone.
Traps
Do not use mass as weight. Do not mix cm with m or grams with kg. A force perpendicular to motion does no work. In chemistry, balance equations before mole ratios. In biology, do not confuse diffusion with active transport, or mitosis with meiosis.
