Great source for plenty of practice

I signed up for Magoosh since the price was right (relative to some books, which can end up being quite pricey). I ended up using it almost exclusively for the Quant section since I studied English in undergrad.

The quant practice is great, and I believe it helped me a lot more than the books for a couple reasons. First, you can set the questions to either adapt to your progress or to stay constant. I mostly stuck on either Hard or Very Hard since I didn't want to risk dropping down to some Medium questions, but others may find that adaptive practice is useful for them. Also, you can either review questions after each answer or do the questions in bunches (sorted by time, or by number of problems you want to do). Pretty useful.

I think the Quant questions have real quality. They were very similar to the ones I got on the actual GMAT in regards to how they were worded. That's good, compared to say the Manhattan GMAT, which has great practice tests but the quant wording is a bit over the top (makes you try harder, I guess, but not as close to the real thing as, for example, Magoosh).

There are also video explanations for each problem (which is nice, but after the first few dozen problems I would just glance over the written solutions and 'get' it). And then each problem links to a "related lesson" video, which is mostly how I went through the lesson concepts.

I didn't watch too many Verbal videos or use it much for practice. I will say, though, that their general strategy videos for each question type are useful (for example, how to approach sentence correction really helped).
