Hey,
First off,be sure of why you want to take a drop.If you are sure of yourself that you would be able to handle all the inferiority complex which is obvious to develop when you see your friends leading a 'cool' life in college.There is a lot of pressure from the family members and from within oneself.You may feel discouraged and irritated at timesIf.But if you trust yourself that with your hardwork you can get through all the ordeals,then you may go for drop.
If you are dropping because of family or any external pressure then i am sorry to say you are going to waste your time.
It's your calling. It should be a well-calculated  decision because it is 'you' who has to put in hardwork,energy,time and everything during that period.
There are certain things that you must follow during the drop phase. Don't let the negative people get on your nerves.Learn to ignore those things that are not good for your mental health. Study hard and treat yourself with moments of leisure.No exam is more important than your life so do take care of yourself. You are your first priority.Utilise this time well and don't indulge in boredom or procrastination.
Hope this helps.
Good luck.
