I have been reading chapters from the MGMAT SC
guide. Towards the end of the book, you find a list of question numbers from the OG split topic wise. So, while going through those I realized that while reviewing any questions from the OG, even when you get some correct, it is good to read the explanations.
In some question explanations in the OG, reasons for rejection of different options are given and sometimes one might come across useful rules or points that one might be getting close to forgetting. More the number of perspectives that you look at a question from, more the number of concepts you can internalize.
Feel free to add SC tips to this post.
