My biggest piece of advice is to avoid trying to memorize everything. The people who write these exams love to test your critical thinking and situational judgment rather than raw facts. My usual workflow involves a quick pass over the core concepts, and then I spend about 70% of my time doing active recall. Platforms like https://www.simplytests.com/ are perfect for this strategy because they simulate the exact style of questions you'll face. Constantly testing your knowledge exposes your weak spots early on so you can focus your energy only on the topics you actually struggle with.
