You rarely will find an educator who recommends cramming for a test or exam.
But does it ever work? Maybe!
According to worldwidelearning.com, cramming for tests that involve memorization might be effective.
So, if you are preparing for an algebra or geometry test, which require you to solve problems, cramming might not be the best approach.
But, if you are studying for a Spanish alphabet test or Chinese test on the numbering system, cramming might just work for you!
