You may be under some stress
, and I do not know if you are aware of it. Find out what this disturbance is all about and as you address it, memory and concentration will happily return to favor you. Do meet with a counselor, if your stress is too much.But you may work on the following: Daily exercise of at least half an hour is a must. Even if you go to a gym, ask for aerobic and/or callisthenic exercises with whatever else you are doing. A healthy body harbors a healthy mind. With regard to memory, it is very important that your brain and body is ideally rested to be able to recall whatever is required, rather comfortably. Puzzles pose problems to the brain that help it to use new pathways and neurons, which give the brain considerable exercise. It taxes the left brain to use logic to solve the myriad possibilities which other activities do not stimulate. Crosswords are excellent for vocabulary learning and use. Jigsaws and Rubik cube stimulate different permutations to finally settle on the most likely one. Picture completion and anagrams help approach problem solving from several angles. Do Sudoku, and memory co-relation activities and skills. Have a good night?s sleep, have a good breakfast of more proteins, meditate often, remain free of stress, eat a lot of fiber (whole grains, fruits and vegetables), nuts, avocado, eat dark chocolate, consume less of fat and use olive oil instead, do Yoga meditation
exercises, etc. You need to check out if you are stronger visual or auditory. The visual is a better mode than the auditory. However, if you combine the two modes, you will get the best concentration. Have a special place of learning, which should be well lit, with soft painted walls, well-ventilated, with no distractions. When you get bored, study by writing. If you repeat learning at least five to seven times, you will apparently remember for a longer time. Sit comfortably but do not slouch. The reading material should be of a fairly large print. Study at small intervals of about 40 minutes and then take a break or change the subject. Short-term memory is a faculty of the left brain, and long-term memory is a feature of the right brain. When people are stressed, they tend to favor the right brain and abandon the left brain, where short-term memory resides. So, it is really very simple: deal with the stress and activate left brain functions. Here are a few suggestions to activate left brain function: shut your left nostril and breathe, move your eyes from right to left and vice versa for at least half a minute at a time, and do callisthenic exercises with some form of counting, regularly. There are some memory enhancing techniques and study methods that your teacher will be able to guide you with. If your home life is full of distractions and stress, it is likely to affect your memory, adversely. In that case, I suggest that you and the family go for counseling too.
