Hey. This question should be answer by you yourself. It is not about what colleges you study in or what course you pursue. It is all dependent upon your interest. If you are interested in doing B.Tech in CSE then you must go for it. If not then go for BCA+MCA dual degree. You must bear in mind that both the courses are different and contain varying subject matters. Going for BCA+MCA from Lucknow University is not a bad option because it depends upon your capabilities and skill development. You can be successful only if you are diligent in your work throughout the graduation period. Hope this helps. All the best.
