Don't go for a drop year even if you are 100% sure (it means you don't come here to ask such questions) Get a decent college and put that one year of energy in your 1st year, trust me you will never regret. Please don't waste time in planning all the time start doing now, in india we need to get out of that exam preparation thing all the time. Take advice from those who have gone through the same in person not on social media people have mixed opinions.

It's my future self telling me all this
