I've been reading the post and they are very helpful.
I have ONLY the OG 11
th edition to prepare. In my country none of the GMAT material is available and things will take months to arrive. ( i even have to leave the country to take the GMAT abroad)
How do I use what I have to the best of my advantage, including all what I can do here ( challenges) to do well. I really am aiming for a great score. 700+
I would appreciate the feedback
