No, don't drop a year just for JEE Mains. Drop only if you are targeting JEE Advance and if you want IITs. Still if you are confident enough that you can do very well in JEE Mains next year and are sure to get top NITs, then only drop the year otherwise it's a waste of time.

If you want to qualify JEE Mains then it is not necessary to take coaching. But if you are targeting JEE Advance and have taken a year's drop for only IITs then you should go for coaching. Preparation for JEE Mains is not that difficult. It just requires consistency and sitting hours. Focus thoroughly on class 11th and 12th.
