Students often have test anxiety. The onset of exams also brings along some tension for students to ace the exams getting good grades. Most of the students fear to appear in exams. It seems to them that they might fail their tests, important exams or quizzes. Test anxiety is something normal to experience for every student but most students complain that it's too much to handle for them, and even as well may be so.
A recent study by Psychology Today in this regard suggests that there lies an associate link between anxiety and memory. The link is evident to exist, but the concept of this link or association between the two is still ambiguous, and the experts are unable to understand it.
Recalling during a test depends upon the positive or negative approach of a thinker. Stress usually does not interfere with long-term memory, which is where the entire learning of the students is stored.
Stress interferes with short term memory. So if the students keep themselves away from negative thoughts and learn the concepts written in the books properly, then the learning is stored in long term memory which makes recalling easier at the time of the test.
So now the question arises that why do teachers take numerous tests at the school again and again.The answer is simple, and it is in fact to improve the learning power. Taking several tests of one specific topic trains the memory storage areas of the brain to store the concepts in long-term memory, and the students are then able never to forget the concepts in their life.
The more effort is put in; the better results are observed. So practicing, again and again, is what students need to apply to get good grades. For this case, practice tests are a convenient option to practice more and improve the learning power.
