hello bhupesh 

jee advanced is one of the toughest exams . first if you are talking about jee advanced you must have to clear jee mains exam as well .however if you are able to do lots of hard work you can prepare it along with your college . in college you will have the access to the college library . also if you got failed or have  backlog in the first sem , then you can clear it further without any loss . however prparation of jee advanced with courses like btech or b.arch would be quite difficult. feel free to discuss in the comments below
