GMAT club tests review

I am from India and I am not so great in quant ( as opposed to many Indians who are generally good at quant). Anyway like everyone i solved OG questions and thought they were OK. But actual Gmat has questions tougher than that. Tougher doesnt mean new concepts, but in way of applying the already known questions and traps. Gmatclub tests for which i have taken a 3 month subscription ( I am 3/4th done thru it) and its a blessing. Bevause you can choose the areas youa re weak at and practice them and solutions by Buneul are great and simple and elegant. My only advice would be if you have more time, try solving all the quant (600 & 700) level questions 2-3 times. That way you are assured a great score in Quant.
