Don't ask for hardest book if really want to do better preparation for iitjee and if u can spend some extra money then u have a good option that is u can apply for 'resonance' iit preparation series...bt its for the last year preparation and if u are in 10th the resonance is not for u. then u can take admission for pre-foundation course in any good Institute
