A couple of days ago I bought some Fuji ProPlus (C41) film but along with that, the guy gave me a roll of Kodak Academy 200 BW film for free, saying it was just lying around in his shop and he didn't want it.

It's great to get a free roll, but I have absolutely no idea how to process this, or how long ago this has expired.

Should I follow the standard procedure of shooting at ISO 100 or 160 (it expired probably 3-4 years ago and probably hasn't been refrigerated) and then processing as usual (I use Caffenol)?
