Dear Hou Ting,
I am sorry that maths disappoint you, but you can’t give it up. As you say, it is one of the most important subject and there is a reason for this.We have to use maths from all the time. Wherever your career takes you, maths will have to be using. In fact , most employers and universities will accept people who have failed or given up maths. All you can do is try your best in maths and make the most use of time you had. If you have trouble understand anything, the first person you should tell is your teacher. That is often surprising how simple things seem when you are explained properly---even maths problems!
