So what causes test anxiety? For many students, it can be a combination of things. Bad study habits, poor past test performance, and underlying anxiety problems can all contribute to test anxiety.

While the pressure to perform can act as a motivator, it can also be devastating to individuals who tie their self-worth to the outcome of a test.

 Waiting until the last minute or not studying at all can leave individuals feeling anxious and overwhelmed.

Previous problems or bad experiences with test-taking can lead to a negative mindset and influence performance on future tests.
