Hi,

Since  you're a dropper so you need need to think for what reason you have dropped 1 year of what you are preparing or it might be your personal problem. If you're preparing for something or any exam you should go in that field only doesn't matter you have invested 1 year. There should not be any problem for what you wanted to do. and this thing does not matter that you're fresher or dropper the most of the colleges accepts minimum 2 years gap. So it not such a big issue.

So if you want to go further for B.Sc than you should go forward with it and if you have good marks in 12th than it may give you free hand over admission process in many good colleges.

Good Luck.
