Hi Shashi,

There is direct admission or BTech lateral entry only if you are a diploma student. This scheme is only for those students who have a diploma background after 10th. They are given admission directly in the second year of engineering for BTech. If you are a diploma student then you can apply for BTech lateral entry.

Else, you will have to answer entrance exams to get in BTech colleges.

For IIIT Hyderabad Lateral entry admission, you will have to answer LEEE which is an entrance test conducted by IIIT Hyderabad for Computer Science and ECE streams,

There is no direct admission process for a science student who has completed his/her 12th, Answering entrance exam is mandatory.
