super difficult subject, we have test 1 (worth 20%), test 2 (worth 30%) and final exam (worth 50%), all the tests are very difficult, consist of around 30 mcqs and 5 essays. they will ask u things that u never expect. you have to remember all the tables, graphs and formula. it changed a lot from the previous smt that was very easy

Don't need to attend any lectures, just let your friends hear whats in exam for you. very easy subject. don't recommend if you wish to learn something.
