Subset review is a review of a portion of the learning material (e.g. before an exam). The portion may be identified with search, by branch selection in Contents, by category, and other means that determine a subset of elements. The reviewed subset material may be sorted by its sequence in the knowledge tree (Contents), priority, difficulty, interval, retention, recency, etc.
Search and review in SuperMemo is a review of a subset of elements that contain a given search phrase. For example, before an exam in microbiology, a student may wish to review all his knowledge of viruses using the following method:
The review may include all subset elements (e.g. Learning : Review all in the browser with Ctrl+Shift+L), or only the elements that are outstanding for review on that particular day (e.g. Learning : Learn in the browser with Ctrl+L). Before you execute the review, you can randomize the review material (Ctrl+Shift+F11), sort it by priority, by recency, by interval, by size, by age (in the learningprocess), etc. You can also apply your default sorting criteria with Ctrl+S in the browser. All forms of review run on all elements except for (1) dismissed elements and (2) those elements that have already been processed on this particular day. The latter condition makes sure that you can do a comprehensive review in various subsets without duplicating your work on a given day. You can overcome the block of double review on a given day by using Add to outstanding (see below).
Search : Find elements makes it possible to define OR-searches and to save search definitions. This way you can, for example, choose a set of terms that define your "diabetes" subset and use them each time you want to review your "diabetes" material.
The parameter Subset in the Statistics window indicates the progress of repetitions in subset learning. This field displays the number of items, the number of topics, and the number of pending elements in subset learning. The name in the parentheses describes the currently processed subset.
In the simplest case of branch review, the button Learn at the bottom of the contents window can be used to execute outstanding repetitions on a selected branch of the knowledgetree. For example, to make repetitions in the Medical Sciences branch, click that branch and then click Learn. Using Learn in the contents window is like using Learn in the element window, except only elements belonging to the selected branch will be considered in making repetitions.
To thoroughly review a branch of knowledge (including non-outstanding elements), do the following:
To randomly review a branch or a subset:
Instead of spending your time on a thorough review of a branch or subset, you may prefer to intersperse the review material in your standard learning process. You can do it with Learning : Add to outstanding.
Add to outstanding is a rationalization upon 2 extremes:
On one hand you can proceed with your outstanding queue, on the other, you can smuggle some subset review in between. For example, you might learn about the superiority of "intermittent fasting" over "fasting". You will want to investigate the subject to perhaps employ it in your lifestyle. However, you do not want the subject to be buried in thousands of articles you keep reading. Nor do you want it to monopolize your learning time on a given day. You can import several articles on intermittent fasting and spread them sparsely in your outstanding queue with Add to outstanding. By the end of the day, you will have a peek at all those articles, have them all well prioritized, and integrated with the learning process (in proportion to the value of the newly discovered content).
An alternative to Add to outstanding is to spread priorities (with Priority : Spread), however, it has 2 flaws:
In other words, Add to outstanding is a more extreme version of Priority : Spread, but not as radical as Learning : Spread in the browser (irreversible rescheduling), or subset review (reversible review).
If you ever neglect learning, you may wish to unload your item backlog ahead of your topic backlog. You can optimally do it with a change to your sorting criteria. However, you can also start your day from 100% item repetitions:
Ideally, in incremental reading, you should have items and topics mixed up. This will help you achieve balance between retention of the old material and the inflow of the new material. By working with items first, you risk slowing down learning by working on high retention. That's a step back to classical SuperMemo.
If you want to semantically connect a group of elements related to a single subject in incremental reading, you can use subset review based on the elements' tree structure created in the incremental learning process. This way you can quickly review all elements related to a topic whose "big picture" became hazy.
You can also choose Learning : Learn branch on the element menu to begin branch learning for one of the ancestors of the currently displayed element. You can use this method if you encounter interesting material that you would like to refresh more thoroughly before you proceed with your standard learning process.
Advance is not a form of review. However, it makes it possible to shorten the intervals and speed up the review. For example, if your exam comes in 100 days, you can shorten all intervals in a subset to less than 100 days with Advance.
The Advance operation will not work on 2 kinds of topics:
If you would like to review the material related to Auguste Comte (1798-1857) do as follows:
If your history exam is approaching and you cannot cope with all repetitions in the collection, make sure that at least your daily portion of history is thoroughly reviewed:
Repeat the procedure daily. However, in the last 3-5 days, you could follow that yet with Process branch> : Learning : Review all to protectively refresh the material that would optimally be scheduled after the exam.
Important! This strategy is not recommended for long-term learning! It departs from the optimum timing for review to consolidate memories. It should only be reserved for situation when burning school situation forces you to neglect your long-term planning.
