My suggestion would be similar to @Rumburak - use Anki.
But (with respect) I would not put a list of “key points” in the “Answer” because (IMHO) a list violates the whole principle of “Active Recall”. With Active Recall, : there must be a single “question” that you will either answer or fail to answer.
So for Chapter 1, the front of an Anki card might be “How well do I know Chapter 1?” The back of the card would be empty. You must then read Chapter 1 in order to answer that question.
You then tell Anki how well you know Chapter 1. Anki schedules the next interval according to which button you pressed after reading Chapter 1:
- Easy: You had no problem remembering everything ( !! )
- Hard: You struggled to remember a lot of stuff.
- Good: Somewhere between “Easy” and “Hard”
- Again: Anki dumps you back to the beginning, and you start all over again.
The problem with the above Anki approach is no different from the problem with spreadsheet approach - it’s all very subjective regarding your assessment of how well you know the chapter. But at least the Anki scheduling will suit YOU personally. A different person would generate a different schedule. On the other hand, the spreadsheet would be the same for everybody (I assume).
If you use the other part of the suggestion by @Rumburak - the use of “key points” - you might prefer to create an Anki card for EACH key point - in addition to the single card for Chapter 1.
The benefit of that approach is that it satisfies Supermemo’s recommendation to split info into atoms. Each atom then gets its own schedule. Very easy atoms are quicky pushed into the future - leaving you more time to spend on the difficult atoms. On the other hand, with Passive Review, you read each word in the chapter exactly the same number of times - unless you Tippex out the key facts that you already know. As you know, the problem with Tippex is that it does not slowly disappear at different rates corresponding to the gradual “forgetting curve” for each key fact. So you need to buy another book and start again. (You might get a refund from Amazon for claiming that the Tippex was already in the book when it arrived.)
As an experiment, you could run the two methods in parallel:
- One card per chapter (passive review + spaced repetition)
- One card per key point (active recall + spaced repetition)
If you want to study only key points from Chapter 1, remember that you can use “tags” with Anki.
So a bunch of cards might have the tag “Chapter 1”, another card will have “Chapter 2”, and so on.
There’s a well-known theory in physics which states that the speed of a caravan in a desert is exactly equal to the speed of the slowest camel. (The slowest camel is always placed at the van.) If you apply this theory to the parallel methods discussed above, then the next date that Anki recommends for the Chapter 1 card will be the same as the date recommended for the key fact that is causing you the greatest difficulty in memorizing.
Maybe you could try that, and report back on your progress.
