SA1 Examination

I think I will need more tution and more work to do!Although I am sastified with my Chinese but I am not sastified with my Mathematics and English.My mother and my relatives told me not to give up and my relatives also told me that if you know that you have already tried your very best,just work harder during the SA2 Examination.They also comforted me.During SA2, I will do my best to achieve better marks.I am also weak on the problem solving.What should I do???
