Hello Aspirant,

Yes, you can still pursue B.Tech in Computer Science if you have a backlog in Mathematics. But for that, you need to check for college because some private universities and state colleges provide admission for B.Tech, provided that you pass the supplementary examination. However, top government colleges and universities have a strict policy that you need to pass all the subjects. So,  it is important to check the criteria before you applying for it. All the best for your future.
