I was trying to solve SC questions from OG12. I got approx 80-90% correct answers while solving the first fifty questions. However, as I am progressing, my success rate is going down steeply. To add, I got only 2/10 correct from 80-90 range. I know that OG12 problems are graded in increasing order of difficulty. Am I the only one who is facing these issues or is it that my basics are not right ?
Any tips will be greatly appreciated. I also tried to solve problems that I answered incorrectly on my first attempt. However, I get majority of them right on my second try. Not sure if I am treading the right path.
BTW, I have already gone through mGMAT SC Guide once. Sometimes I get frustrated and I feel as if I should open the grammar book.
Please help.
Thanks
