Sir,it is tough or easy to pass in preparatory course in iit
Hey!
Nothing can be said about the level of exam, as emtioned by different candidates, some students consider it to be difficult more than the jee advanced and those who clear the exam consider it to be easy. So, it overall depend son your preparation and the confidence in a particular branch. also, if youwouldnot be able to clear the exam then your whole year would be wasted. and next year again you will be preparing for jee exam and further for advanced. So, decide wisely, I'll suggest if you are getting any good NIT then you must opt that , however decision is yours.
Thankyou
