With 20 years experience in helping learners and faculty pursue the goals of education ever more successfully, we've learned a thing or two about the practices of the most successful students. And while we would never claim a constant or direct correlation between grades and learning, it's difficult to learn successfully and not be able to demonstrate that fact effectively. So, without further ado, here is our general advice on how to be an "A" student. If you find them useful, there is a pdf version available through this link. Feel free to share the tips with your students.
 

Clarify shared expectations in the course

Ask, “What is expected of me?” and “What do I expect of myself?”

Create a plan of action

Determine how you will meet the course expectations.

Make your commitment to success in writing

Share it with another person.

Prepare for class by reading for learning

Don’t just read; read and think and ask questions. (Use a Reading Log or take notes with inquiry questions)

Think critically in class

Ask or write down inquiry questions, connecting what you are learning to what you already know. Follow up on any questions that remain once class is over. Find the answers to your questions.

Teach someone else

Pass along your learning to someone else as a way to test and increase your understanding.

Demonstrate your learning and increased understanding before the next class meeting

Use it or lose it. Find ways to use what you have learned.

Extend your knowledge

Create a new problem to solve or try applying your learning in a new context.

Anticipate future challenges so there are no surprises

Stay aware of all assignment and requirements, starting any work early enough that you are not rushed by deadlines and due dates.

Execute readiness preparation for every performance task

For a test, take a practice test; for an essay, write a draft. Find a way to practice or rehearse.

Let go of your fear and stress

Finish your preparation for a performance such as a test not less than 24 hours before the performance. Studies have proven that relaxing and getting plenty of rest before performing yields better results than cramming or practicing up until the last minute.

Engage in assessment and self-assessment after every performance

Regular assessment of your performance by both yourself and others will help you strengthen and improve your performance.
