I got so much help from you Stacey, but just one more question with IR.
The Manhattan Prep book says that IR score of 4 and higher should be okay. Does that hold true even nowadays? (the book was written in Dec 2014)
I'm really struggling with IR. My IR scores from three MGMAT CAT have been 0, 5, 3.8 (My total scores are 690, 740, 700 on those three exams). My current strategy is to guess all three MSR and do the rest. I just want to find out that getting around 4-5 is still alright like the book stated. My target schools have GMAT average of 640~680. So I'm good on Quant and Verbal.
