End of Pimsleur

I’m now very close to the end of Pimsleur’s German III. I’m up to lesson 20 which overall is lesson 80 out of 90. I have just realised however that there is a 10 lesson set called German Plus designed to go after German III but my library doesn’t have it. I still recommend it to anyone wishing to learn a language, at least if you can get access to it for free. Pimsleur, German
