Hello Kunal,
Don't worry about your marks as many colleges accept 50% in PCM so you may go through them as your interest is B.Tech so don't leave your interest as your marks are low.

You can easily get admission in a private college based on your +2 percentage like CGC, CU, Amity, etc.

Hi Raushan,
Yes, you can. Maximum colleges require a minimum of 50%. You will be eligible for most colleges if you have 50% or above.

Hi,
You only mentioned science, but I assume your subjects were PCM. If yes, then popular options are:
B.E./B.Tech
B.Sc
BCA
B.Arch
Defence
Navy
CPL
and so on.
If you have interest subjects other than engineering you can see B.Com, BBA, B.Sc LLB, etc.

Hi,
Let me ask you, what do you mean by a 'good job'? Have you decided, what kind of job do you want?
