I took Knewton about a year ago. Hated it. It was a waste of time, money and concentration.

The GMAT tutor is different. Their program goes through the quant (which is what I need help on) very well. Whenever I have had a question the tutors have emailed with the answer. Finally, at least for me, confidence seems to be a large portion of the test. The staff over there has been very supportive and has made me believe that I can succeed. I haven't taken the test yet, and am still working through the problems, but this program has really helped me move in the right direction.

I've decided to take the GMAT on February and after 3 week with the official guide I understood I needed more help. I've signed up to this course on March and I'm about to take the test this Monday, 10 and a half weeks later, yet I've finished most of the course (over 90%), while working full time.

For those who never took the GMAT, this course is great. It forces you walk through everything. I have a strong math background and it still helped me with the tricks needed for quick and efficient solving. The course simplify complex subjects, even the hard-to-nail probability with combinatorial questions.
In the verbal section, this course do wonders with SC. I started with a very weak sentence correction and now I have a great statistics of about 1 mistake for every 10-11 SC I do. In the reading comprehension and the critical reasoning I found the explanations good but not great, so it is now my weakest point.

The biggest problem I found with the course wasn't in the content. It was the UI and the statistics tool. The website only tells you your stronger and weaker points but does not change it as you get better at certain point. The statistics tool only tells you how much of the course you have completed, and no statistics of the success rate of the different subjects, which was much needed for me. At some point I started my own statistics and wrote down on a paper where I was wrong or right. It turned out that my statistics were completely different from those presented to me at the course website.
As for the UI, there is help window on the side of every question. A great idea and really helpful, only it's about a square inch and the content needs more than that. It's really tiny and you can't properly read what is inside. The same goes for the home screen where you cannot easily find the subjects you want to revise, it's just a long,long list of subjects.
Moreover, no android app so I couldn't enter the website from either my phone or my tablet. That's a shame, because I spend almost two hours everyday going to wok and back and this time could have been more productive.

Overall, I recommend the course for those who do not need a boost in just one subject, but a complete start-over. It is thorough, and teaches you almost everything you need to know.

Good luck!

I took the GMAT last year in July and did miserably. My mock tests were good, but my exam bombed big time. So I thought something was wrong with me on the test day. But I decided not to give up and take the exam another day.

I was researching for some courses online, and I read about the 70 point assured increase in the GMAT Economist course. I payed 1$ and went through with the course for a week! I realised how intensive the course was and how well planned it was. I paid the rest and started cracking.

The course has an option of choosing between the math and verbal sections or allowing the software to choose the pace for you.
I went with the software as there is a fine balance between both the sections.

The basics of math which I needed to brush up, were neatly presented and explanations were made simple. This, along with some sums after every concept was very useful. In the verbal section, there was an intense focus on sentence correction, which I think I needed as I am not a native english speaker. The CR question types were covered strategically. The explanations for how to crack the RC's were good, but I felt there were not many questions in this field.

Another highlight of the Economist GMAT prep is the fact that its extremely easy to review the concepts you have studied. There is no need to take notes, because its already there! So, before each test, reviewing concepts were made easy.

I used the classes for both math and verbal and the teachers were extremely smart and helped me (I left these for the end, something which I regretted. If I had cleared my doubts regularly, it would have been better)

On the exam day, I was well prepared but I was still a bundle of nerves.
My score increased by 90 points, but I have not reached my target score yet.

Im not giving up, Ill definitely beat the GMAT one day.

I would recommend the Economist GMAT Course to both people who have taken the test and those who haven't as the course content is extensive and it adapts itself to your skill level! Definitely worth the investment!

I've been studying with the GMAT Tutor from the Economist for about a month now and I am definitely seeing improvements. I've yet to take the real exam so it is hard for me to throw out numbers, but overall I would sum up my experience with the course as positive.

pros:
- practice anywhere, anytime
- set timed sessions ranging from 5 to 60 minutes
- built in "timer" questions that help you to build a perception of how long it's taking you to answer certain kinds of questions
- feels like a competitive video game so the content is pretty easy to get through

cons:
-a little bit hard to jump around although their is an option to choose what your session covers
- not yet sure how score estimates compare to real test
- no AWA questions provided - you have to get prompt from elsewhere and submit essay incl. question for a grade.
