What to do, I failed in maths in first semester of my diploma?

if u weak in math so do other courses otherwise concentrate highly on that subject

Don't loose hope just practice more and more You can also take guidance of any mathematician or do group study to know your weakness. All the best! !

come and join our FALTU college. lolz you need to clear all the basic terms of maths. and take a look of previous year model questions paper for easy preparation.

focus on logic.. everyday need practice min 1.5 hours.... do practice

It's bad that you failed but don't worry that's when you learn what to do, so just clear it and study well.
