If you want to join GYEL it is a commitment, but you should also enjoy it. The weekly meetings are fun and engaging. Use office hours less for help and more for enrichment; going above and beyond. My main advice to you, is to not procrastinate. Do NOT wait until 2 days before the homework deadline; do it ahead of time, and refine it a little closer to the deadline; 90% of it should be done by the week before. I would say as far as change-making; you can do anything. No matter what it is; even the smallest thing, it will have a ripple effect.
