From 310 to 600 in 6 Weeks

When applying to Mannheim University I saw the Term GMAT for the first time in my life. I did my research and just went for it, bought the test, scheduled an appointment and started studying. I have not solved one math problem since 2015. I had to relearn everything because it was just too long ago. My English speaking was always good but as everybody will learn that doesnt really help your verbal score. I took my first practice test (official) before starting to study and was really embarrassed because I scored a 310. That was the point when I decided to go for GmatWhiz. I really liked the Webinars so I knew they will be a good source. Well 6-7 weeks later, I studied for approx 5 hours a day on average, took 2 weeks off work. The crazy thing is also that I was already admitted but needed to provide the GMAT results to approved in the end.
About GmatWhiz
I really liked the guys. I am very impressed about Saquib (i hope i didnt butcher his name) math skills. The section and topics are very well organized and give you a very good intro into each topic, for quant and verbal. It is quite frustrating in quant sometimes to practice because the questions get very fast very difficult (for me). Even when it is explained in the video it is sometimes just hard to follow because all of my math from Uni already forgotten.
In general I can really recommend GmatWhiz. They have a fair price and are always available to contact or set up a meeting if there is anything you need.
Good luck to everyone and happy studies!
