Good Luck. Hope it helps.

Yes, don't worry if you hadn't studied CS in +2. You'll get to study every topic from beginning in B.Sc. But, you can still study programming languages on your own, through the internet.

Yes, you can get the admission easily, because you got 70% in class 12th and that's good.

To pursue BCA you can join from Science, Commerce and Arts background. But, to pursue B.Tech or B.Sc CS you'll need a solid background of mathematics. B.Sc CS is a General Course and BCA is a Technical Course, so getting job from BCA is easy than B.Sc CS. After B.Sc CS you can do M.Sc CS or MCA both.

Yes, with this rank there is a chance to get free seat in this University.

Hi Manojna,
Getting computer Science engineering with this score will be difficult for you. Although, I will suggest you to give a try and participate in counselling. If seats are vacant in final round, then only you will get admission. Otherwise, very low chance is there. Best of luck.

Let me be frank, you percentage is very low and you will find it difficult to take admission in Galgotia for CS. But, for once talk to their admission cell.
