Thank you for your quick reply to my question.What you select it dependent on how WES (or whichever Educational Credential Assessment Service) assesses your degrees. They might only assess your Associate's and Bachelor's Degree together as one 4-year Bachelor's Degree (if you're lucky - these services often tell people that their non-Canadian Bachelor's Degrees are equivalent to less than a Bachelor's, or that their Master's is only equivalent to a Bachelor's etc.). The only way to tell for certain is to get the assessment completed.
I want to register one science class in January 2018, so I can earn an Associate Degree in Science in the same community college. I only need that one particular class to earn another associate degree. I took pre-Nursing courses at the same community college in the US before I decided to switch to Accounting major. If I get another 2 associate degrees plus a bachelor degree (Total 142 credits), hopefully I can get more points for my EE application.
