I never run into those issues. I use about 6 courses, and the English sentences have always been grammatically correct.

There's nothing wrong with memorizing example sentences. Your brain is not a digital memory bank, memorizing is impossible without forming some deeper understanding on the fly.

What I mean is, DL refuses to teach that deeper understanding. You have to beg in the comments to identify a declension.

And the memory thing - I don't have to think about what a sentence means. This is phrasebook teaching, a piss-poor method.
