Hello dear student !

If we talk about which course is tough among BSc and BTech, then this totally depends upon the student and his interests. Both courses are difficult as both includes physics and mathematics of good level . But of course as BTech course is of 4 years whereas BSc is of 3 years, so BTech is one year more of exams and study so it is little tough. Also the subjects it includes are more of technical. But scopes in this are also quite better .

Hope this will help you
