Personal experience with Magoosh?

I actually have a couple of questions...

1. When students send questions to Magoosh, Magoosh doesn't answer questions outside of their resources and (maybe) ETS... If I sent them a question from, say, a Manhattan GRE Strategy guide, would they be inclined to answer? I'm trying to decide whether to go with Kaplan and Magoosh, so I support with answers is a must for me because I'm relearning a lot of concepts from Manhattan + Magoosh (if I don't understand Manhattan explanations).

2. What kind of support did you use to improve your analytical writing score, especially with receiving feedback for your practice essays?

3. Overall review of question quality for Magoosh? I'm definitely a beginner in math, but I'm looking for a quant of 153+ (preferably 160) and I'm starting at 141.
