Hello,

So, first of all what you did is phenomenal honestly. I know you must be stressed but see the thing is most of the students take at least a year gap after 12 for preparations. Obviously you will be questioned about taking a drop year but if you fill the companies CGPA criteria and have proper knowledge in your field you will get a good placement. It depends on your hard work and focus. Other than that I don't think it would affect your placements that much or at all.

Good luck.
