Science

Not surely possible. Still, you can take a chance to apply for university, but chances are 98% no. Good luck.

There are many few Institutes which offers training in M.Sc Zoology and these Institutes will not be providing training up to the desired level hence it will be better that you prepare for the entrance exams through self-study. Refer books of your B.Sc. Which will be helpful for the entrance exams.

Diploma is 2 year or 1 year course. Graduation is 3 year course. So, if your course of Diploma which you wanted to do is 2 year course, you have to complete 1st year. Any institute or university don't gave admission in directly 2nd year.

It is completely other side of the river. Commerce student can't pursue Bachelors in Science in any subject as in physics chemistry biology. It became very difficult for you and you cannot cope up with Science. So it is better that you opt for your own line commerce and don't waste that 2year study
