The 60-Day GMAT Study Guide

I am following the study guide, and I was supposed to finish the ratio today.
I watch the videos and then solve the OG problems, whenever I watch the videos I am doing great. I pause and solve it myself and then replay and everything is perfect.
Once I turn to the OG I am in big trouble, more than half of the questions are wrong, or right by guessing
I do the error log and I found like 40% of my mistakes has to do with the strategy of solving, 20% has to do with choosing the wrong rule or concept, the rest are careless mistakes.
So what should I do?

Make specific notes about how you can recognize the strategy issues in play. "(If I see a variable in the answer choices, maybe I can pick a number." "If I see that the answer choices are numeric values, maybe I want to back-solve" etc.) Do a little drilling on the rules that gave you issues. Then gear up to take a practice test. Ultimately, it's not the percentage of questions you're answering correctly that's important, but cultivating strategies that will help you adjust to the nuances of the exam.
