In this channel, you can see informative videos, Aptitude classes for competitive examinations, recipes etc.,

Aptitude classes will be useful for all Competitive Exams.
My Suggestion would be : Students should practice for solving Aptitude problems, from their first year of UG itself. 
Then it will be easy to crack campus recruitment written exams , MBA entrance exams 
& all govt. / Private job related exams (which involves aptitude problems in written exam).
