Hey MetallicaFan,
Great questions. Here's what you need to know:
1. If you have any questions, you have our instructors and the entire community of Knewton students at your disposal at answers.knewton.com. You can post any type of question there, and receive feedback from teachers and peers. Our Premium Live course also allows you to chat openly with your teacher and classmates during class, or ask private questions to off-camera teachers for one-on-one feedback.
2. We can't answer questions from the Official Guide, but we can certainly help you with the underlying strategies and concepts. So, if you're working through the OG and find yourself struggling with a question, you can talk to a teacher about the general concept/question structure, and we can work through a similar Knewton question.
Hope this helps! Let me know if you have any other questions.
All the best,
Jessie
Knewton GMAT Team
