Each part is available for the limited time shown only. If you answer more than half of the problems on a given part correctly, you get the 1 point for that part. If not, you can try it again and keep trying again until the deadline for that part. If your eventual total score out of 10 is higher than the average of your other quizzes, I'll average this score in as another quiz, which will raise your quiz average. Otherwise I'll ignore what you do on these web problems. Thus not doing them won't hurt, while doing them can help, not only by raising your quiz average but also by making you better prepared for the Gateway exam and any other exams and quizzes that involve integration (i.e., almost all of them!).
