Hello,

It is not winter semester. It is odd semester and other one is even semester. Passing criteria is you appear all the exams like class test,quiz,suprise test,lab valuations and have written your semester paper well.

minimum mark is 50%.if you score 49 then you will get D grade. but why to get. try to score betwen 60-70 to get B or C grade. but thimking about to just pass then your CGPA will decrease and it will be problem when time will come for placement. It is true that no one checks marksheets but CGPA is a eligibility bar kept everywhere until you gain 1-2 year experience.

So think before you do anything. But what you will do  in your free time. Study will help you lot latter. So be sincere. Better not be book warm but keep track of lessons and just know what is happenning.

Hope it helps!
