Folks,
I have been studying GMAT for the last 4 months seriously.In the 4 months I have attempted twice most of the OG problems and have identified weakness areas.After the 4 months preparation my ETS Paper scores have risen about 30 points.I originally scored 520 and now I scored 550.Though,it is frustrating I am determined to progress.
I have identified my Quantitative weakenss in 2 dimensions:Concepts + Practice.Incidentally my concept problems lie with advanced concepts such as Proability,Combination,Modulus Operation,Geometry and Inequality.I will be studying the concepts deeper for these topics.As for Practice,I am looking for challenging problems for concepts such as Numbers,Fractions,%,etc.What will be a good source for such problems.Unfortunately,I have not been able to find a list of say 15 challenging problems on Numbers on GMATClub's category based problems. Any advice on this? I would like these practice problems to be close to the style of real GMAT exam.
As for Verbal, I have finished most of the OG problems. As I am still very weak in Critical Reasoning, I have resorted to LSAT questions. Is that advisable? In addition, I am running out of questions for S.C.? Any recommendations on sources where I can find good questions? Rgds,
Anna
