I like anime. Anyway tell me only truth, reality plz
i have only 6-months i am a repeater with only 78% in hsc.
are 6 months enought to study for jee main only
or they are enough for jee main + advanced.
i am losing hope as time is passing.

Your main focus should be on mains right now. As very less time is left, dedicate yourself to the concept building according to mains syllabus. Once you qualify mains and if you have your concepts clear 1 month time between the mains and advanced paper is enough for advanced preparation.

Right now focus on mains . Solve as many question banks as possible 

Hope this helps you. All the very best
