What is that?
I was offered this credit for AP... and obviously.. with the asterisk, it's not an actual course code...
Can anybody fill me in on what they mean?

I googled it but did not get any informative results.
If I had to guess I would say that perhaps that credit can be used toward any biology course you would like. I.e. If you wanted to have a credit for Bio 1M03 without doing it, perhaps this could "fill in"

I would recommend contacting Kathy McIntosh at [email protected]. When I emailed her, she replied within the day

haha yeah, I did email her, but she was taking longer to get back to me, so I decided to ask you guys first.... you guys are faster

You could also try calling at 905.525.9140, ext. 23049

Oh and she specifically said not 1A03 or 1M03

Did she reply already?

It means that you have a credit in a course in biology, but you don't have credit for a specific course. For example, if an employer/program you're applying to/etc required that you've taken a biology course, you qualify for that. However, you don't have the prerequisites for any courses that require credit in 1A03 or 1M03.
