A student must complete all quizzes, postings, and midterms to receive the boost to his/her course grade with improvement on the final.

To receive a boost to his/her course grade with improvement on the final, a student must complete the following steps:

1. Complete all quizzes: This usually involves studying the relevant material, attending classes, and making sure to take each quiz by its deadline.

2. Complete all postings: This could refer to online discussion posts for the course. The student should make sure to contribute to all required discussions, providing thoughtful and well-written responses.

3. Complete all midterms: Similar to quizzes, this involves studying the relevant material and taking the midterm exams. Midterms are usually more comprehensive and require a deeper understanding of the course material.

By completing all these tasks, the student will be eligible for a grade boost should they improve on the final exam. This means that if the student's grade on the final exam is higher than their previous grades, their overall course grade may be adjusted upwards.
