There is very less possibility to apply for JEE Main Application form now.

If you want you can apply for other entrance exams of engineering like BITSAT, VITEEE, Manipal, SRMJEE and Amrita.

All these are top private colleges which provide good knowledge, exposure and placements.

Application form is already out in case you want to apply.

For government colleges you can apply for your state level entrance exam.

All the Best!!
