Hello,

It will take 4 years to complete your Btech after Bsc. Btech is a undergraduation course which requires 4 years. Many colleges can provide you admission based on your choice of programme by merit or by entrance exams. So yes can you do Btech. If you want you can also do Msc or MBA because if you have already completed your Bsc then it is good if you continue your further education instead of spending another 4 years in degree. Choice is yours. Thank you and all the best and check out below link for colleges and information about btech
