Please choose the correct ending to complete the given sentence: Youth: [header] How to graduate grade 12 [title] Ensure that you're taking the right courses. [step] When you get your list of classes, double-check to make sure that they're what you wanted, and what you can handle. Some high schools actually recommend not having a full course load and leaving yourself a spare block in grade 12 so that you're not overwhelmed.

Ending1: Also, some of your classes may need to do some studying. Your high school grades will decrease the more you complete courses. Ending2: Make sure that you're not in classes that are too difficult, either. It's great to challenge yourself, but taking advanced math if you barely passed last year probably isn't a good idea. Ending3: [substeps] If you're taking the same classes multiple times, you'll find that economics classes are much more competitive. If you are already into economics or creative studies, maybe it's a good idea to take that as well. Ending4: [substeps] Check with your school to see if there are classes you can take in addition to taking honors courses. Some courses are poorly managed, or require you to work on coding and programming.
