Modern Physics (Unit 1) - Relatively simple unit. But some derivations you may find difficult to derive during exam if not practiced “writing and study” many times.
Quantum Mechanics (Unit 2) – only a few questions examiners can ask from this unit. Very easy and understandable but problems sometimes may make you a bit nervous.
Electrical conductivity in metals (Unit 3) – Very easy unit and some of the portions already covered during your PUC.
Dielectric and magnetic properties (Unit 4) – Many equations and some derivations may make you skip this unit but just refer previous university question papers where you can find only 4 questions which are always repeating.
Laser (Unit 5) – It’s a natural choice of all students since it is very easy to understand.
Optical fiber and superconductivity (Unit 6) – Optical fiber part is very easy but you may find some difficulty in grasping some superconductivity concepts.
Crystal Physics (Unit 7) – Easy unit but if you are not good in drawings better avoid this.
Material science (Unit8) – Very easy unit. Since this unit includes latest topic nanomaterials, a threat of unexpected questions exist. Otherwise both nanomaterias and ultrasonics are easy to handle.
