is that really tough to crack jee main exam

No, if you are studying for sufficient hours with good plan and have good foundation.

No, nothing is impossible, as ‘Impossible’ itself says that ‘I M Possible’,.........you just need to be determined, and with a single mind having a clear idea for your aim you have to move ahead with these tips –Stay focused on your studies and keep in mind that one must focus on Physics, Chem and Maths, try to fortify these three, take some coaching classes from a reputed place like Akash Inst etc, then to download previous years’ question paper of JEE mains and advanced and practice solving them, try to enhance speed to answer maximum questions in lesser possible time and finally appear in Jee mains – do well – then appear in JEE Advanced – do well again, It would be better if you would mix the subjects that is do Physics for two-three days, then, may be shift to some topic of Chemistry or Math. This would help keeping things not-exhausting.Now, once you have brushed up a topic, solve some random problems from a book specifically on that topic.Now the most important task during all this is to mark the examples or formulae you find difficult to remember and then keep an eye on IITs/NITs counselling rounds and thus institutions are allotted otherwise there may be second option to visit the official websites of some renowned institutions offering technical studies....to name a few – Lovely Professional Uni, Phagwara,..........................DTU, Delhi,................PPR Inderprastha UNi, KArnal,...................BITS Pilani Hyderabad Campus
