Struggling to Remember During Psychology Revision – Any Tips?

There was this method regarding flashcards in the book I'm reading that helps me study anatomy and physiology. As a past A-Level Psych student, I think it'll help with Psych too, since both are quite up there on the challenging scale in terms of how much content there is to cover.
Make flashcards as normal. Term or question on front, definition or answer on back. Make as many as you need.
The trick is when you're looking at these flashcards, and how often.
The book tells you to make 8 sections, in the form of small boxes or anything you can put the flashcards in and have them clearly separated. These sections are: "card", "today", "same day", "24 hours", "3 days", "1 week", "1 month", then "learnt". As you can see, they're timestamps. If you don't have a month then you'll have to cut it short, but hopefully that's adequate.
All cards in the "card" section. You're meant to take around 10 cards out every week, but since you said upcoming I'm going to assume you don't have the time for that. Because of that, put all cards in the "today" section. Take your cards out section and go through them one at a time. Try to answer it correctly, and if you don't put it at the bottom of your pile. If you get it correct, put it into the next section ("same day"). Keep going through them until they're all in the next box. You shouldn't need to look at your notes as you did when you wrote them then reread them if you got it wrong. Then, you wait until the timestamp on the section your cards are in, then repeat.
Go through cards in "today" and put them into "same day". Later that day, take them out and go through them, then put them into "24 hours". 24 hours later, take them out and go through them, put them in "3 days". 3 days later— you get the idea!
I didn't do this but some variations of this method suggest you to put a card you got wrong in the previous box, instead of in the next so you revise it earlier and can't progress that card until you get it right.
Another would be mind maps that you repeat until you remember. First, without giving a damn about presentation or headings or grouping ideas together, brainstorm. Topic in the middle, then you write every idea you remember about the topic branching out without looking at your notes. After, group related ideas using different colors. Then, you can start the mind map. Topic in the middle, then for each colored group decide a heading. These headings will be your first branches, then you can add the ideas branching off of those headings. After, go over your notes and add what's missing. This is where it gets boring: study that mind map then cover it. Try redrawing it. Compare them after, study what you missed, then cover and try again. Do it until you are satisfied or remembered everything!
Little side note: a layout I recommend for mind maps is the tree layout that travels right rather than down. I find your typical mind map a bit too chaotic; having all ideas going in one direction rather than all directions is easier on the eyes.
You probably have already been told past papers are a great revision technique, but, if you have the time and a nice teacher, ask if they mind marking it and telling you where you went wrong. Looking yourself where you went wrong is not always reliable and you easily miss things, this will let you know exactly where your weak spots are.
For future reference: Start studying after your first, proper class. After classes, once I was home I would go through my notes again, grouping ideas together with different color pens, and making a separate page to write down all main points without using full sentences. Just headings, keywords and little doodles. Then, I'd use the mind map method I said above, and revising it after certain timestamps. I see a lot of people who leave revising until exams are closer. This may work for some people once it comes to exams, but it never works for long-term memory, which is a bit of a bummer if you need the information for your future education. Especially since the amount we forget within one day without active recalling is much, much more than people realize. There's multiple studies on this, but search up 'ebbinghaus forgetting curve' if you're interested.
I keep mentioning revising the same topic after specific timestamps of revising them the first time. No matter what revision method you use, make sure you do this! There are many studies on how spaced revision is more effective at building long-term memory than one-and-done or cramming. The timestamps I mention are the ones the book said and that ended up working for me. But there are other patterns out there, like 2/3/5/7.
I've used mind maps for planning as well! Separating the different topics into sections and then splitting the topics into subsections to learn individually in blocks makes it a bit easier and a bit more organized. I won't move onto the next block until I can confidently recall the first, and I can tick off the ones I have done. Mmm, not a great example as it's been awhile, but think Attachments. Attachments written in the middle, then one branch could be "theories", which branches out into different theories under the attachment topic. One could be bowlby's theory, another could be learning theory, etc, etc. You wouldn't be writing the specifics as this is just a mind map for knowing what to study next. A good idea would to keep in mind the topics Assessment Objectives (AO1, etc.). The theory itself is obvious AO1, but then you should add a weakness then a strengths branch to cover AO3's.
My friend used to write down the different AO's and their content in a clear and concise way for the recent topic after class too, something she could look over quickly rather than search through her notes for it.
While writing this, the website is giving me related discussions, and some are about past high-achieving Psych A-Level and current university students giving tips on revising. Go take a look!
Hope this can help you a little, and good luck!
