Re-read the statement...."already learned", meaning its been learned at some point in the past. Example...what if I worked for a summer doing the books for my fathers business where I did payroll, bank recon's, paperwork prep for the bank loans, etc. What are the odds that with only that experience I could pass the Accounting 1 class? Trust me, the odds are pretty high.
I dont think Sunshine is looking to cheat a system...instead, he's advocating streamlining the process by capitalizing on prior knowledge and experience...and for that I applaud him.
