Hi singh8891,
So, how was your timing in the previous exams? Also, how were you scoring in your previous exams?
Your main issue here seems to be that you purposely went slow in the verbal section, right?? I understand that you may be gun-shy because of how things went with your previous exam; however, purposely slowing down probably is not the answer. On your next practice exam, if you have extra time, you need to be aware that another Reading Comprehension passage will show up.
On another note, panicking is a score-killer. So, any time you feel the urge to panic while taking the GMAT, you need to just continue to do your best to get correct answers, rather than compounding whatever issue is causing you to feel like panicking.
So, let’s see how things go with your next practice exam. Feel free to report back with any updates.
Good luck!
