Once you've learnt something you need to be able to recall it when you need the information, such as when you are sitting an exam.
The problem is that most people tend to forget up to 80% of what they've learnt within 1-2 days of learning it. If this happens to you it's because you stored the new information in your short-term memory instead of your long-term memory.
Reviewing your work regularly can help prevent this happening
How to review your work
Study your work, using whatever method you choose, then:
- after about an hour, try to remember all you can about what you've studied.
- revise any material you've forgotten.
- review the material again the next day.
- review it again after a week, then a month, and again just before the exams.
In other words, apply the 1 + 1 + 1 + 1 method and review your work:
- 1 hour after learning it
- 1 day later
- 1 week later
- 1 month later.
This should help fix the information in your long-term memory.
