H i, first of all congrats for your 12th percentage and qualifying JEE Mains but I would like to tell you that Thapar University is one of the top most universities of India...

So, getting admission in B.Tech specially computer science is not possible.. But do not lose hope. You can try in other private colleges for another branches of B.Tech as there is much scope in another branches also..

Rest depends on your passion to achieve something in life..

All the Best for your future..

If  you think I have been able to answer your query you may rate my answer...
