The answer is: Cramming for a skills test can lower your performance and increase your test anxiety.
Cramming refers to the act of memorizing a lot of information within a very short period of time.
This method of studying is considered to be very inefficient. It does not provide enough time for the learners to have a full grasp of the materials since they can only memorize the materials very briefly. Because of this, they would most likely experience anxiety during the actual test.
