Primary Schools offer additional help to bring immigrant children up to speed with their german, though I'm not sure how many families use this option.
You can also almost always switch tracks, the farther down you are one track the harder it gets to switch up. I went for the second lowest (Realschule) and then went to a tertiary school (Fachoberschule). With that I can study in a University for Applied Sciences (different from normal University).
The german education system has many options open, the general push in the lower two tracks is to get you into a job as early as possible (there are lots of job fairs I went to) but still permit you to pick any of the other 20 options.
