Yes surely you can get BITS Pilani without prepration without doing anything. Why BITS Pilani you can get IIT Bombay CSE without doing any Prepration for exam . Just go to bed and sleep and start dreaming then you can get any college.😅😅
And sorry for this bad joke but are asking this silly questions is also not good. Means you can’t get this type of college without doing a hard work and prepration. Preparing does not means only getting in coaching it can be done by yourself at home by hard work.
But don’t ask this silly questions again.
