Education is the Key of Life

I am 16 years old and am in form two student in a secondary school in St TERESA's SINYERERI.
I am bright boy since I passed my KCPE exams well. I always pay attention in class but when exams come the results are not good and this quite discouraging.
When I do my exams I walk away feeling I will perfom well but afail.
Please if you need my care give me an advice on how I can improve my grades I would like to be a journalist or a teacher in future.If you want to give me advise please contact my father through 0702289147 or sent an sms.
