Well, you can't opt for any branch in B.Sc because it is allowed only after PUC (Science) and commerce students are not allowed to do it. But you can pursue the same in B.Com.

For that you should contact the admission department of that college and get relevant information about the eligibility criteria and entrance exam details for that college, then you will have a clear path towards study in that college.

I don't think presidency offers micro biology. You can check with the admissions department, if you want.

1. Aware College Of B.Sc Medical Lab Technology
2. Balaji B.Sc MLT College
3. Chandana B.Sc Medical Lab Technology
4. DDR College of Medical Laboratory Technology

Yes, you can do B.Sc in IT in lateral entry scheme where you will be in 2 year directly. So, only by spending 2 years, you will be completing your B.Sc degree.
