I DON'T KNOW I PREVIOUSLY WHAT HAPPEN TO ME.......I JUST FEEL THAT I LOOK LIKE NOOB IN THE CLASS.......ESPECIALLY MATHEMATICS T .....THE TEACHER TEACH SO FAST UNTIL I CAN'T CATCH UP WHAT IS TEACHER IS TEACHING. FURTHERMORE , I ALSO FEEL LIKE I DIDN'T CONFIDENT TO STUDY STPM BECAUSE PERHAPS I LACK OF TUITION AND PLAN TO STUDY MYSELF.....I THINK ABOUT MYSELF BECAUSE I WANT TO RELY ON MY ABILITY AND NOT RELY MUCH ON TEACHER.....I WANT TO TRY SCORE WELL IN STPM RESULT JUST DEPEND ON MY ABILITY.....ALMOST ALL MY CLASSMATES APPROXIMATELY 80 PERCENT THAT ARE HAVE TUITION IN ALL THEIR SUBJECTS....WELL , THAT NOT MEAN THEY CAN SCORE WELL IN ALL THE EXAM .....ACTUALLY I FEEL THAT RELY ON YOURS ABILITY IS THE MORE IMPORTANT IN CONTINUE TO YOUR STUDY ....SO HOW I WANT TO OVERCOME MY PROBLEM??????
