Hello Vijay!

Your planning is really good but do you think that these targets are realistic to you?

Is it wise to set such a target where even a slight mistake will ruin your effort. While studying if money issue will keep penetrating your mind then you won't be able to focus well on studies and you will be in pressure.

It isn't easy to hit 10 Cgpa all the time. 

I'll suggest you to try for education loan. You will pay that after getting your b.tech done or you must go for some government college instead like most students do.

All the best!
