Honestly, consistency.
Some days you may feel like not completing your assignments while others you feel like flying through a whole course which is understandable. When certain courses seem boring find the most interesting or frustrating thing about that course and let it motivate you instead of intimidate you if that makes any sense. You got this and congratulations on graduating so soon. Also for keeping grades up make sure to study hard, pay close attention to details (especially the ones that can help you get out of sticky situations) ex. paying attention to certain keywords within your booklet, consulting the instructor by clicking the help center in the "What would you like to do?" panel, and talking to other students may help, we also have the Student library and Webinars you can attend to help you. It would be great to meet you at the 2017 graduation. Remember you can do this!
Good luck in future studies,
Macaya
