Kolbe syllabus for Foerster's Algebra & trig..

[Michelle in AL]

Does anyone know where I might find one of these used? $55 seems a bit high, but it seems to have extra lab exercises included. Is there a used Kolbe board?
Thanks, Michelle in AL

You might want to try cathswap.

It might be a good place to ask. But, a WTB on Cathswap would reach more potential sellers.

Thank-you both. I don't belong to either of these groups, but will check it out.
