Hey Kkadvent,
I wanna jump on this too, if you don't mind. It sounds to me like you know what you have to do, and you're not doing it. When you say "I'm going on instinct," I would say: "Well stop!" In other words, if you can't do it with grammar...don't do it at all. Review it after the fact and learn what the grammatical issues were. Then do that same question again, a week later. This time, you should know the grammar. If not...rinse and repeat.
Final thing: Go through the entire OG and categorize every question without solving. In other words, keep a running list on a separate piece of paper, like this:
1. Modifiers, SV Agreement
2. Parallelism, Modifiers (meaning?)
3. Pronouns, Parallelism
4. Verb Tense
Do the whole thing that way, then check your work in the back of the book. Remember, you aren't solving any of them, you're seeing how quickly you can categorize. Give yourself 20 seconds max on each question to find the categories, then move onto the next. Do 20-30 at a time, then check yourself. This'll help you get into the mood in terms of categorizing. Good luck!
