Hard Quant questions with targeted quizzes

I have purchased the bundle of e-gmat verbal online course and GmatClub premium membership along with GmatClub tests year subscription. The quant questions were harder than the actual GMAT and I rarely crossed the 49 raw score in GMATClub tests. The tests provide a solid base to test the key areas such as Number properties, Inequalities, Algebra, Geometry and Equations etc. The Data sufficiency questions test the tricky and subtle concepts. Bunuel provides excellent explanations below each question. The harder questions have forum discussions with multiple ways to solve. The Verbal section of GMATClub tests is also useful as it has some dense RC texts and tricky CR questions. I would definitely recommend to use the GC tests in preparation to the exam.
