Sorry to learn of your disappointment. The first thing to do is to relax and then get in control of the situation. You've already done part of that by posting your question. We still have time to get raise those practice test scores!
At the moment, it's somewhat difficult to identify the main issue without more information. How, exactly, did you study the eight MGMAT books
? Did you incorporate an Error Log
with the three OG books? Did you time yourself with the OG questions? What are your strengths? What are your weaknesses (the topic in which you need to improve the most)?
I have a few suspicions of what might have contributed to your practice score, but let's find out what you have to say first! We're looking forward to your response.
