==Answer==
You evaluate a class, performance or skill based on the basic requirements (aka rubric) for that effort. It is like a report card. So, for work you would say you are a hard worker (available for overtime, multi-tasking skills), are great at job duties (what you do best--troubleshooting, fast assembly, rapport with the customer) and so on. So, set up your rubric and then state your abilities for each item.
