Hey Mani Kant,
For B.Tech admission your should have passed your 12th with PCM with minimum of 45% marks. JEE mains is the main entrance exam conducted for B.Tech. Other than B.Tech here are many universities which provide various entrance tests for the admissions like BITSAT, VITEEE , KIITEEE , UPSE , SRMJEE , Manipal ,etc. So you can also apply for them. While many of state boards also take admissions on the basis o score of JEE .
Hope this information will help you.
Best of luck..!!!
Thank you.

Dear Mani Kant Jha,

In order to do B.Tech/B.E course you have to appear for entrance exams of engineering.

You can appear in JEE (Main+Advanced) to take admission in IITs/NITs/IIITs and GFTIs. To be eligible you should have 75% marks in your boards exam or you should be in top 20 percentile for general category. For SC/ST you should have 65% marks. 

To take admission in top private colleges you should appear in BITSAT, VITEEE, Manipal, SRMJEE and Amrita.  

For government state level colleges you should appear in your state level entrance exam. 

 

Good Luck!!
