Final answer:
Test anxiety is a genuine psychological condition with both physiological and cognitive symptoms; it can be assessed with tools like the RISB and managed with professional help and strategies.
Step-by-step explanation:
The statement "Test anxiety is all in one's imagination" is not entirely accurate. Test anxiety is a real psychological condition that can affect performance on exams. It often involves physiological symptoms such as increased heart rate, sweating, tremors, and GI discomfort, as well as cognitive symptoms like racing thoughts, inability to concentrate, and blanking out. Tests like the Rotter Incomplete Sentence Blank (RISB) can help reveal underlying anxieties and other emotional struggles.
