Hi shrigovind !! Hope you are doing well!! This question can not be answered clearly as it completely depends on you that what things are you interested in and what kind of course and things you want to study and pursue for your future. Both the courses are not so easy, btech (computers) include a lot of computer related studies like programming and software so you will have to study those stuffs while in BBA you will bee studying about business and management stuffs. So you will find that course easy which excites you more or which have your interest more. Thus follow that course with which you want to build your career.
