Hi,
These are the 2 universities in which there are many colleges you can get: University of Agricultural Science and university of Horticulture Science.
Hope for the best.

You can go ahead with a Masters course or even a Ph.D. It depends on your persistence and choice. Research in the field of Biomedical is gaining a lot of interest in past 2 decades. You can end up finding a good research or industry career too.

Yes, 90% chances that you'll get IET Lucknow because lateral entry depends on the vacant seats in second year.

According to me, further study is the best option for B.Sc. graduates. It is the area where you can explore yourself in multiple areas as per your interest.
B.Sc. degree also has excellent employment opportunities. Jobs for B.Sc. graduates are not just restricted to the field of Science but also they can explore others areas like management, law, etc. You can work in various areas which include both Science & non-Science fields.
I would suggest few Masters programme:
MBA (Master of Business Administration)
M.Sc. or Master of Science
MCA or Master of Computer Application.

Any degree that you do adds to your competence as well as strengthens the job claims. In you case, if you are already working with M.Sc. And B.Sc. This will enhance your claim in Higher Education. I suggest that you should do B.Ed that will be more beneficial for school teaching careers.
