Strongly recommend!

I bought the EGMAT online focused course which gives you 2 months' access. Very comprehensive and quite reasonably priced, would strongly recommend this, especially for people who prefer interactive videos to reading off a book.

For quant, EGMAT does a great job of dealing with bite-sized basics and the concurrent practice quizzes help you test yourself on individual concepts in an incredibly precise manner. I followed the course from top to bottom.

For SC, I went through the EGMAT course (~30 hours) - covers everything - verbs, pronouns, modifiers, comparisons, parallelism, and idioms. EGMAT keeps things simple and easy to comprehend, avoiding any unnecessary grammar jargon (which GMAT does not expect you to know either).

I found EGMAT mocks' difficulty level to be quite close to the actual exam.

I've put up a slightly more detailed debrief as a post.
