Dear student,

For semester exams and particularly 1st semester you don't have to study vigorously from advanced level books or don't have to take load.
The basic thing is notes. Just study form the lecture notes and do atleast 10 questions for each topic.

The basic thing to pass a semester exam is - just remember the lecture notes and you must have atleast more than 75% attendance.
Also in your practicals perform well and your mid sem must be up to the mark. If you don't have lecture notes then you better obtain it.
