I'll give you an example of why you lose your memory when taking a test. You study really hard for the examination. You remembered everything the night before. You go into the classroom, you're taking the exam and all of the sudden the information isn't coming back the way it did the night before. You walk out of the examination room, the stress is kind of relieved, however the information starts to flow again. Now, it's a little too late. You can't go back and tell the professor, "I knew it the night before." That stress has blocked your mind temporarily. All of the sudden it's as clear as a bell, as it was the night before the test, when you got out of the classroom. Stress does block your mind and memory.
