Dear Shailendra,

In order to take admission in engineering colleges you have to appear for the entrance exams.

To take admission in IITs/NITs/IIITs and GFTIs you can appear in JEE (Main+Advanced). To take admission in top private colleges you can appear in VITEEE, BITSAT, SRMJEEE, Manipal and Amrita. To take admission in your state level government colleges you can appear in your state level entrance exam.

Good Luck!!
