This ad though looks new, it's the from the same old person.
This guy has spent a lot on online marketing for sure.

It may just be my innate bias, but I'm never overwhelmingly impressed by people who can't be bothered to spell/grammar check their own ads - especially if part of what they're selling is how to improve your sentence correction skills.

I know nothing about the guy at all, although that free "bonuse" material is tempting!

haha

On the topic, though, I think under certain circumstances you could beat the GMAT in 30 days. I studied for two months, about 5 hours a week. So, I suppose I probably could have achieved the same success in half the time, with 10 hours a week.

However, I got a 1500 on my SAT, and worked as a private math SAT tutor during college. I think a similar foundation would be necessary to get a score like I got in just 30 days.

I think the GMAT questions are really fun (yes, maybe I'm a little sick), but still, I can't imagine studying 20 hours a week for a month. I think 5-10 hours a week is much more realistic, especially if you are still working like I was.

Best wishes,
