Hi, B.tech is considered to be a better degree than B.Sc. Technical knowledge is more needed for today's society for problem solving to research. Even B.Sc has its own advantages where in a lot of interesting fields open for masters. JEE paper 2 and NATA are exams related to B.Arch (Architecture).

The semester exam date is same for all semester. It doesn't matter, whether you are lateral or regular in any college.

Computer Science has a very high demand in present world and even in the future due to the upcoming technologies.

Upon my range of knowledge, there is no exam for Anna University, so in order to get admission, you should get 990+ in +2(if you are an Andhra student or the other) for Tamil Nadu native students. It may ranges from 980+.

Will you frame the question correctly as we mentors are not able to interpret it?
