B.Sc

I would suggest you CSE as the world is growing rapidly and so is the technology. You have completed class 12th, you can join CSE or BCA.
All the best.

Dear,
Minimum eligibility criteria for civil services is graduation from any UGC recognised university. So, after B.Sc, you are very much eligible to appear for civil service exam. Suitability depends on one's interest and skills for in-depth study towards the subject taken in under graduation level.
Best wishes.
