Hi, i have a problem, please help me, i'm in Day 11 in GMAT 60-day plan, and i studied every part gave it all the time to understand it, but when i do the exercise i don't know how to solve,and the answers is something that would never come cross my mind , i thought about two things,i do all the study part now and postponed the exercises later because they made me so frustrated. OR i study them too like if they'r a part of the lesson and solve then again at the end but then it will take a longer time to finish the whole GMAT study...
