in 12th my percentage is 70 can go for direct admission in b tech

Hey!

The basic eligibility criteria for B.Tech is:

Students must pass the 10+2th examination from any board in the science stream in order to be admitted to B.Tech. programmes. If a student is interested in or wants to enrol in a B.Tech. programme, it is recommended that he or she take the PCM (Physics, Chemistry, and Mathematics) group of subjects as their main subjects, as these students are preferred for the programme.

Admission Process:

Various entrance examinations or tests are offered in institutes across the country for Bachelor of Technology or B.Tech. courses.

Institutes use entrance exams like JEE Main, JEE Advanced, BITSAT, and AP EAMCET to screen applicants based on their merit. These admission exams assess prospective engineering students on the fundamentals of engineering, as outlined in their 10+2 curriculum.

So, one is required to give these entrance examinations for admission in B.Tech courses.
