I am worried about the calculation mistakes that I maybe make in the final exam, which would affect my grades related to the rank and further learning.

This worry derives from the math test I just mentioned in the previous joural and I really care about the consequence.

I unconsciously think if I don't do well in the final exam, how bad I would feel,which influence my current mood and cognitive perception.we are prone to think the negativity and worried about the  non-essentials.

It is the time that I can choose to focus on the parts which I am able to take charge of,like preparing hard, checking carefully rather than worrying unproductively.

we all have a inclination to magnify and over generalize the negative.

But by no means should we ignore the fact that our brains are malleable thus we may as well embrace ourselves because anything does not happen for the best and learn to have a growth mindset, meaning by rituals ,striving, self - fulfilling, however hard it is , we could eventually achieve the things that we are crave for
