Make Your Own Abbreviations!

"Taking class notes takes a lot of concentration, and making your hand write so much can be a challenge! To make it easier, come up with your own system of abbreviations before you start taking notes.
Having a system of abbreviations allows you to write more calmly and legibly in class, while taking down more information in your notes at the same time.
An abbreviation can range from something common (“w/o” for “without”) to something more complex and specific to your needs (“ImpMo” for “Impressionist Movement”). Just make sure your abbreviations are ones that make sense to you and things you’ll remember when it’s time to review your class notes."
