Hello Aspirant,

Year drop after school is advisable if you're into getting good colleges and need some time for preparation, you can use this time to figure things out and decide what career you want to pursue, research about different colleges and courses and apply accordingly. Just keep this in mind that while applying for admission next year you'll be supposed to present a gap certificate, provided  and signed by the official judiciary of the court in a stamp paper. Rest it is completely fine.

Hope this helps!
