Hi there, nice to meet you all!
This has been a long time coming, but I have finally added a brief description of my GMAT experience in my blog:
https://rubicksjourneys.wordpress.com/2018/03/04/navigating-the-gmat/I am very happy to say that I achieved a score of 710, without paying for any tuition or premium tuition packages.
There is some very useful free content out there, which I have detailed in my blog entry above.
The key for me was a lot of studying of the areas that I was less strong at.
If anyone has any questions then I will be happy to help wherever I can.
All the best
Nick
