Science

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 of accounts business studies economics. Take decision deliberately. Best of luck.
