I went to consult Ms tan in this early morning. Now, i am waiting for my friends at EA room. They are taking their breakfast, so that they do not need to went down from library later. After that, i have bst test at afternoon. In fact, i no yet do a full prepartion. I just remember what i can recall back from the lesson. I think that today will be a stressful day for everyone. Eventhough this bst test only occupies 10% in the final assesment, but it always decides whether you can pass or not.
