Assignments
Start early (even if it is just reading through it)
Work to understand a concept outside the context of an assignment — use a 'playground' or 'sandbox' folder on your computer or even something like Codepen or JSFiddle, then apply your understanding to the assignment.
leave yourself time to review and revise an assignment
Seek out help! Running into roadblocks? Read through an MDN doc! Check out the textbook! Attend or watch sections! Ask a question on Ed! Communicate early with David or your TA through the Canvas Inbox!
