This is a sheet for the 6 tenses in german. Each will have an example of how to conjugate weak(regular) and strong(irregular) verbs, and when the tense is used.
This should be read in the order of Present tense, Simple past, Present perfect/perfect tense, Past perfect, Future tense, Furture perfect.
The PDF messes up the order and a lot of things overlap, i would suggest reading this here and not in the PDF.
There will be a Dictionary at the bottom for refrence
