Worth it!!!

Very often we find ourselves in a situation where we are done with the official question and still lack confidence and hence in need of some extra practice question ..of course you will find loads of question on gmatclub for free but then how would you gauge your progress and strength / weakness ...to me I found my answer to the above question in scholaranium..
Though the question for CR are a notch extra difficult then the official question but they will build ur stemina and help you in pattern recognition skills ...though I never got more than 55%ile in ability score ..I hung up there and finished each and every question on CR ...The best improvement I got through scholaranium is in RCs ..I used to finish OG RC with decent accuracy but will always find myself missing the timing by around 2-3 mins in a passage of 4 question ..and with scholaranium I was able to find my weakness in Type of question (e.g Detail type) and Subject of Passage (e.g Humanities) where I use to lag ..after that it was all practice for another couple weeks on Scholaranium (about 15-17 passage ) and I started getting 85% accuracy within time pressure ...
