Have you ever walked out of a test and thought “That exam sucked”? Most, if not all students might at one point or another feel that way. The reason being, the vastness of content to be studied; or simply not understanding the whole purpose of the Taylor series, you just implemented. However much effort you put in your studies, there is always room for more. Work hard. Getting a bad grade can ruin your present day, but don’t let it ruin your next day. A bad grade is a reflection of how you studied, and not a reflection of you!
