Sir, I am a student. I have good memory, understanding, thinking skills, but I am very slow in processing information in my mind, learning new things ,forgetfulness,poor concentration, mental fatigue, especially when a task has time limit to do, like any competitive exam or even normal exam I am not able to complete it on time and moreover, I do not catch things as speedily as I was able to catch when I was kid. When I was 14 years of age, I started facing this difficulty. I took a lot of time to understand even the simple things and I need repeated revisions to gain some degree of perfection in a subject , whether practical or theory, a page which any other child of my age is able to retain or understand in a few minutes, I need some 20 minutes for the same. ie. exactly double the time of what a normal student would take. And this problem never existed earlier when I was a child, and over the years it has increased much more. I had good speed of writing and reading , but in exam I need much more time to think and my brain takes a lot of time in processing information and then coming to conclusions. Moreover, I am able to finish my english exam much early, but subjects requiring thinking , I always fall short of completing the exam on time.what is its reason? I AM good in studies, just what I need is more time in understanding concepts or in solving mathematical problems, calculations, I am good at chess but when it requires speed or there is time limit to finish game I can't. SO, PLEASE TELL Sir what is its reason??? And how can I get rid of it.
