Hi, I am not an expert either. Like Karishma says correctly, I also mistook Verbal too casually. Now as a non native I realize blunders I did.
If I were you, my simplest approach will be:
1. Analyze your practice scores of verbal - which specifically is your weak area
2. Take an appropriate course (I took
MGMAT and EGmat both, as non native speaker, in SC the latter helped me more)
3. Re look into your preparation materials
4. Don't time yourself immediately (realized by my own misdirections, it only resulted in frustrations)
5. Refer to books suggestion in forum to improve RC (very important for non natives)
Most importantly don't rush for exam dates, be confidant of your practice status before giving it another shot
All the best
