Hi! I think if you are doing well in MGMAT quant consistently, I dont think you need to worry. However, if your scores are fluctuating, like mine were then you may need to work more. Any pointers for me to improve the Quant

?
Regarding SC, it takes a lot of time and patience. One one of the Thursdays with Ron lecture, Ron mentioned of making sure you study both correct and incorrect answers. So basically stay away from SC resources that do not explain why each option is correct/incorrect. See where your weaknesses are using the OG12 Grid and focus on those first. Later you can mix them up with other SC questions, to see if you can still find the errors.
All the best to you as well.
