In theory, the lab reports were supposed to be writing training. In practice, I learned more co-authoring papers with more experienced folks than all of those could conceivably teach me. In writing, I think #9 leads to #6 when we're talking English. Often miss the ball writing descriptions under graphs, too.
There's much more emphasis and dedicated effort on teaching us presentation, though. You can't defend a diploma without giving one, and we had proseminar and seminar on both levels training us in basics of stuff like voice projection, fighting stage fright, winning/keeping audience's engagement, making slides etc. And it was a lot of fun, too! To balance it, Patent/IP law was hell.
