———————————————————————————-REVIEW INSTRUCTIONS——————————————————————————————

Thorough review is critical to the learning process and for most people should take a significant amount of time (and effort!) potentially equally or surpassing the amount of time taken to do the question set.
1. Redo questions that you got wrong or struggled on without looking at the answers or explanations. Think. Rethink. Push yourself. Put pen to paper. Don’t review with only your eyes!
2. Once you’ve solved or if you aren’t able to solve in about 10 minutes carefully review the explanation (if provided). Again, put pen to paper and redo the question along with the explanation.
3. If we haven’t provided an explanation or if our explanation didn’t clear up your doubts google the first few words of the question and confirm the solution on the GMAT forums.
4. Except for CR and RC, take a screenshot and add it to your dropbox review folder so you can easily revisit the question when assigned review in your HW schedule.
5. Bring questions that you still find difficult to QA or to our sessions. For sessions add the screenshots to the “review in session” folder in your dropbox.
Here’s a video outlining the review process: https://www.youtube.com/edit?o=U&video_id=X6k3niNoGuA

This is a crucial part of the preparation so let’s make sure we get it right. If you have any questions contact andrew@atlanticgmat.com or luciano@atlanticgmat.com.
