Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. I suggetst you worry too much about academic matters. That could be the reason for your problem. Academics are academics. Even if you fail in one exam, there is another chance within next year. Concentration / span of attention is low for all youngsters. Reasons are lack of interest, vastness of text etc. Make studies creative. You need to alter your life style so as to suit the requirement, change your thinking patters and maintain positive body metabolism. Psychotherapy techniques, yoga, meditation etc should help you achieve these requirements. A trained psychologist / psychotherapist can help you in this aspect. If you still need my help, please describe the whole problem in detail and post a direct question to me. I shall definitely help you with psychotherapy techniques to over come your problems. Hope this answers your query. Available for further clarifications. Good luck.
