GATE Scores

Yes, having two Bachelor's degrees, one in BCA and the other in B.Sc. Math, along with a good GATE score, makes you eligible to apply for admission to M.Tech programs in IITs. However, the eligibility criteria for M.Tech admissions vary across IITs, and you will need to check the specific requirements of the institute and the programme you are interested in. Typically, for M.Tech admissions in IITs, candidates are required to have a Bachelor's degree in engineering or technology, or a master's degree in Science or computer applications with a minimum percentage of marks, as well as a valid GATE score. However, some IITs may also accept candidates with a non-engineering background, like in your case, based on their academic performance and other criteria. I would suggest you visit the website of the IIT where you want to apply and check the eligibility criteria for the M.Tech programme you are interested in. It's also a good idea to check the admission process, application deadlines, and other relevant information on the institutes website.
