If you have done your 12th with maths/business, maths/computer application as one of the subjects and in English you have scored 45% or above that you can pursue BCA. After BCA you should think for MCA to complete the journey before joining job in IT domain.

You would need to complete Bachelor's after 12th before you pursue Masters. The eligibility for Bachelor's in HM is 12th pass with 50%.

Hi Shivam,
There is no definite answer to this. 12th boards are not easy and 10 days too less a time to prepare, if you have revised earlier you should start solving previous years question papers and check important notes and questions provided to you by your teachers. Learning something new won't help this late and revise the important topics you attempted the previous day, keep at least an hour for the previous day revision.

You can go for CLAT. This is the only course which has less use of PCM.
