Before you graduate, you must pass the Second Language Certification test. Your results determine if your French has reached an acceptable level for graduation with a French-immersion diploma.
The Second Language Certification test is part of the FLS 3500 course. This is primarily an independent-learning course that prepares you for the test. It does not earn any university credits. You will only receive a grade of "Pass" or "Continue" that does not affect your average.
You may take the test whenever you wish, but make sure that you complete it before the end of your final year. It is strongly recommended you take the SLCT before your final year to avoid problems with graduation.
