A1 German/ English dictionary, Grammar and course books for beginners.
I lived in Switzerland for 15 years and got to B1 level in German and I knew enough French already.
German is quite a hard language to learn, even with instruction.
I've forgotten it all now, of course.
But it is good to be able to speak multiple languages. It gives you insight and it is always fun.
