solar won't let me add commerce 2MA3, 2FA3 and econ 2X03. it says failed when i click verify, all these courses are required for my program. here is the link to the course calendar: http://registrar.mcmaster.ca /CALEN...nt/pg1227.html
if anyone could help me or direct me to someone who can i'd greatly appreciate it

did you take econ 1b03 and/or 1bb3 (and pass them)?

You are sure you have all the prerequisites? For some reason Econ 2X03 is only for commerce students.... but since it's required I suggest you get a waiver for this course. The best thing to do is talk to the registrar, maybe it's a bug in the system. If not then you'll have to talk to the professors in each course and ask for a waiver...

yep i passed both econ 1b03 and 1bb3

Ill vouch for this as well as a few of my other eng & management friends.
I took both Econ 1B03 and 1BB3 in my first year of eng. However, I am not able to select Econ 2X03 as stated in the requirements for Mech & Management II, as it states that I do not have the pre-reqs.

And I passed both 1B03 and 1BB3 with flying colors.

I think you'd have to contact the Commerce Department first. Explain you're an Eng & MGMT student and you need the course but don't for some reason are failing the prereqs. It could be a SOLAR issue. I was denied entry to a class for 09-10 where there was no prereqs but SOLAR said I failed them.

And if Commerce doesn't help you go to Eng and tell them Commerce is being unhelpful, and hopefully they can make sure you get the help required.
