That’s a pretty tough situation to be in but it’s not end of the road…
Although, SRM fortunately follows relative grading mechanism let’s look at average marks of a student at SRM:
In any subject:
CT1: 30/50 = 6/10
CT2: 30/50 = 6/10
Models: 55/100 = 11/20
Surprise test: 3/5
Attendance: 3/5
Total internals: 29/50
He needs to score a minimum of 60/100 in end semester exam to be sure of passing the subject with 59/100 as final score fetching either a C- or D.
In your case I assume you would have total internals around 21(3+6+6+3+2)…
You need to work very hard to score more than 70/100 so that you get around 55/100 as your total score!
All it takes is a little effort and commitment to score marks in engineering! It’s always better to have a hefty internals than keep worrying at the end!!
Enjoy learning more than everything and lead a happy life(that’s what SRM is all about)
