I got stuck by some mathematics problems in the afternoon, which made me a bit frustrated and upset for a while. I thought I could have done it well .
Unfortunately, the fact was that I failed to do so. I transformed my perspectives.
In another way, it reminded me of which parts that I am not proficient in and I could have a orientation to make efforts to synthesize all the materials inside of having no clue about revision.
it doesn't matter in the long run and this time I feel more confident about mathematics final exam for the hard work that I have already done and would be done.
