Five ways to improve your grade with Mastering

1. Give yourself enough time to complete assignments.

The provided estimated assignment completion times can help you plan your work to avoid any late penalty that may apply.

You could lose time on online assignments if you lose your internet service unexpectedly. If this happens, all of your submitted answers are saved. (Losing your internet does not stop the timer on a timed assignment.)

2. Keep working, even if you don't know the answer.

Avoid choosing Request Answer. You won't get credit for questions you answer this way. Avoid choosing Request Answer if you can still get some credit for late answers.
When available, use hints. It's usually to your advantage to open hints.
An adaptive learning engine tracks items you have trouble with on some assignments. Then you receive tutorials or similar questions in an Adaptive Follow-Up for another chance to learn or practice similar material.
Avoid guessing on multiple-choice questions. You'll almost always lose points if you're wrong. About the grading of multiple-choice questions

Answer feedback and review can help you get the right answer. Answer feedback or Review links to the eTextbook can guide you to answer correctly.

3. Pay attention to how assignments are graded.

The grading policy can vary from assignment to assignment. When available, check the grading policy for individual assignments for details about the number of answer attempts allowed, late penalties, and more.

Don't lose credit to cheaters. Don't share your Pearson account with any other students who say they wants to "try out" Mastering. Any wrong answers will count against your grade. Your account may also be flagged and you could be suspended from the Mastering course.

4. Use provided study resources.

Pearson eTextbook — You can add notes, highlights, and flashcards in your eTextbook. When available, play a Channels video for better understanding. The Pearson+ app for your eTextbook lets you study on your tablet or smartphone, even when WiFi is unavailable.
Dynamic Study Modules — When available, use these to test your knowledge, close gaps in your learning, and then retest yourself. Your instructor may also assign Dynamic Study Modules for credit.
Rework items for practice — You may be able to rework some assignment items for practice to help prepare for exams. Your instructor controls whether this is available for an assignment.
Study Area — When available, check out the Study Area from the course menu for self-paced learning and practice activities.

When assignments allow you multiple completion attempts, take advantage of this to keep your best score on the assignment.
Automatic item scoring helps you to identify areas of weakness in the moment.
Dynamic Study Modules can help you to retain information so that you can be better prepared for other coursework.
Studies show that if you work a little each day on your assignments, you'll do better overall in the course. By the end of the term, most students not only like Mastering, they'd recommend it to other professors and students.
