I m thinking about 1 yr dropping and next yr give Jee again is this a right Disition?

It totally depends on your aim. If you are determined to take admission in top NITs then you can take a drop for a year. Otherwise, you should take admission in other colleges. There are many good private college who consider JEE Main marks to take admission. If you are taking a drop for a year make it count be motivated to crack your exam because it effects your placements.

You should give as many as entrance exam like BITSAT, SRM, VIT, Manipal and Amrita as they are top private colleges and provides very good placements.

Below are the top private colleges which accepts JEE Main score

Good Luck!!

It depends on how much hard work you put on this year

Firstly, I would like to know what was your JEE Main rank this year.

If you are confident that you will be able to crack the JEE exam next year by adopting the right strategy and planning then you can go ahead with it.

However, if you have cleared the JEE Main exam this year  and if you are getting admission in a relatively decent college and a branch of your choice, then I would recommend that you take admission and pursue your B. Tech. There are a plethora of opportunities that are waiting for you.
