The 2357 Study Method

The 2357 study method is a spaced repetition technique that involves scheduling your revision sessions at increasing intervals: 2 days, then 3 days, then 5 days, and finally 7 days before an exam.

To use it, mark your exam date, then count backward to schedule your first session (7 days before), followed by your next session 5 days before, then 3 days before, and finally 2 days before your exam. This method aims to improve memory retention by reviewing information at strategic, spaced-out intervals. 

How to use the 2357 study method
Find your exam date: Determine the date of your upcoming exam. 
Schedule your first session: Count back 7 days from the exam date and schedule your first revision session for that topic. 
Schedule subsequent sessions:
Count back 5 days from the previous session and schedule another one. 
Count back 3 days from that session and schedule another. 
Count back 2 days from that session and schedule your final review before the exam. 

Use the intervals for active recall: During each session, don't just passively reread your notes. Instead, use active recall by quizzing yourself, writing down key points from memory, or solving practice problems related to the material. 
Be flexible: You can adjust these intervals based on your learning pace and the difficulty of the material. You can also use the gaps between your scheduled sessions for additional study time or to catch up if needed. 

Why the 2357 method works 

Spaced Repetition: Reviewing information at increasing intervals takes advantage of the "spacing effect," which shows that we learn better when information is reviewed over time rather than all at once.
Active Recall: This method forces you to actively retrieve information from your memory, which strengthens the neural connections in your brain and improves retention.
Combines Techniques: By integrating spaced repetition and active recall, the 2357 method helps to lock knowledge into your long-term memory, making it easier to recall during the exam.
