      Actually no, competitive will even be difficult if sir was not there on UA-cam because completion of the cource won't guarantee your selection; it all depends on consistency .see sir has over 6 lacks subscribers still videos get 20k views or max to max 25k .which proves all subscribers don't view every video and who watch each and every video may not practise questions. Self discipline is the key to get selection

    Guys another very easy method of finding DBE is to take its maximum hydrogen containing alkane and subtract the hydrogen (given) from alkane and divide by 2
    For example : for dbe of c3h6
    Max hydrogen for 3 c is in c3h8(propane) so 8-6=2 now divide this by 2 to get dbe sk dbe is 2/2=1
