Katsumi made an amazing list of study tips for IPT in a thread that you should check out. I used Mr Brightside's notes along with Samuel Davis and Excel book. Tbh Mr brightside's notes were a bit lacking in some areas, and sometimes you could tell they were just paraphrased from either excel or samuel davis. Cuz of that i would go through the interenet and other resources there when i came to a topic that i was iffy about.
Also inbox me if you need help with anything, cause ill be happy to help! i have an example of documentation and a major project that got full marks that i will be posting up here eventually, but havent gotten round to. Keep an eye out for when i do, if you're interested though!
