E-Gmat Scholarium Review

This is an excellent instrument to improve your quant skills. The tasks are challenging and really hard. I would assume that the tasks are of a 700+ level. I was using it mainly for polishing my skills after completion of general course and using OG. It is very structured and very convenient if one wants to understand where is the weakest spots in his/her preparation. You could track your performance with the detailed break down by different types of skills required. My abilities have improved substantially (at least 5 points on a quant section). I would advise to go through e-GMAT quant preparation and then practice with Scholaranium.
