I learned heaps about heap management
I had a blast when attending the Corelan Advanced training. I learned heaps about heap management in Windows and exploitation. Furthermore, during the training a lot of concepts became a part of my reversing / exploitation skills such as: vtables, pointers, IAT and ASLR. Although I was familiar with most of these concepts, during the training they became more clear to me, since they were building blocks for the heap exploitation course. The training is provided at a fast pace and Peter is able to create a great environment for learning. I did not only learn how the Windows heap works, but was able to use the learned concepts to understand the basics about the Linux heap manager. Within a week of the training, I solved my first Linux heap CTF challenge, without any previous knowledge of how the Linux heap worked :)
