Dear student,

If you are doing a B.Tech course, then be it any branch or specializations, generally the courses are of 4 years duration.

Now, in each years there are two semesters, so total eight semesters are there in B.tech.

Now, after every semester end, you will have to give examination to pass the semester. So totally you will have eight major exams in your B.Tech.

Having said that, there are some mid term examinations too in every semester and it depends on college if they take it or not, but most of the colleges take mid tern examination in each semester before the end term examination of the semester.

The things is branch independant, and you will find the system in B.Tech  aeronautical engineering too.

I hope this answer helps you.
