Hope this may help you

Hii aspirant
You need to give entrance exam to pursue engineering in India
Some private institutes conduct their own exam
For NIT JEE mains
For IIT JEE ADVANCED
For B. Arch JEE mains 2
And other state entrance exams as well
If you want direct admissions then you can go for management seats
In some colleges where fees would be 3 to 4 times more than normal fees
And some good colleges where you can get admission directly without paying such high fees you can go through following link
