I can not able to achieve good marks in spite of my hard work. Because the lesson which I read and it's subject matter evaporated from my mind. So when I go to revise them it takes much time to revise And re understood it. I know that I am strong into math but I can't able to perform well either math or literature subject. Though I tried my best to get enough score but my all effort become ineffective. Presently I am preparing my self for joint entrance exam. But this product develop in me when I passed my 10 th standard. After 10th standard ; I was unable to Score well in my academic life. So my 12th standard was worst. Till that time the problem is alone will me. At class 12th I was found as a student with ocd; by a psychologist. Now what should I do?
