Great for supplementing your prep

Magoosh is a great way to review GMAT material on-the-go or under-the-radar while at work. The platform lends itself well to putting 10 minutes aside and doing 5 questions in the middle of the workday. I can't think of any other platforms where one is able to do this so it's a no-brainer to sign up. It's also very inexpensive compared to other products. The instructional videos that they offer are also quite helpful though I wouldn't depend on them exclusively. Magoosh is best used as a supplement to Manhattan GMAT (the most thorough prep available in my opinion).

My only complaint about Magoosh is that their higher level quant is not very difficult. They could used more questions in the 720+ range. Otherwise I highly recommend signing up for Magoosh.
