When I started preparing for GMAT, some friends advised me to buy Manhattan Prep CATs and use GMAT Club to supplement my learnings from the former. However, having the membership of both the CATs and the forums, i found GMAT Club to be a more flexible and effective in terms that it was more conducive to my learning style. The dynamic learning experience through the forums is undoubtedly enriching. The structured analysis of the CATs was very useful and allowed me to identify my weaknesses and hence improve scores within the stipulated time. I have suggested my friends who have taken the exam after me to use this platform as their main material for preparation.
