The SANS course material has helped me improve my skillset. I have learned so much in such a short time period. This course is very hands-on and we are able to get our hands dirty right away. There aren't too many courses that can do this. I would say that there isn't anything that I dislike about this class. I have learned so much in such a short amount of time. I highly recommend this class to anyone looking to learn more about cyber security. I am learning how to use tools like Metasploit and Burp Suite. I am also learning how to write exploits. I am also getting better at writing scripts for pentesting.
