I've been studying cybersecurity through TryHackMe, and I've been wondering about the best way to retain what I learn.

When I study a new Room, I usually understand and remember the topic pretty well while I'm working through it. However, once I move on to another Room and start learning something completely different, I gradually forget parts of the previous topic.

This makes me wonder whether I'm approaching learning the wrong way.

Should I try to memorize everything before moving on to the next Room, or is it normal to forget some of what I learned and come back to it later?

My current thinking is that I might actually retain a topic much better when I eventually need to use it in a practical situation. For example, if I learn a technique today and then encounter a situation weeks later where I need it, I would review it, use it in practice, and probably remember it much better afterward.

At the same time, I'm wondering if I should have some kind of regular review system to prevent myself from forgetting too much.

For those of you who have been studying cybersecurity for a while:

Do you try to memorize everything before moving forward, or do you keep progressing and review topics when you actually need them?

I'd also be interested in hearing how you organize your revision/review process while using TryHackMe, HTB, or similar platforms.
