Narrative:

When departing cmi I was assigned an altitude of 3500 ft on a 330 degree magnetic course. When departing champaign class C airspace I should have climbed to 4500 ft MSL for the 330 degree magnetic course. Instead I stayed at the assigned altitude until encountering the other aircraft at 3500 ft MSL near fennimore, wi. After the encounter with the other aircraft I descended to 3000 ft MSL until reaching my destination. I was getting flight following from champaign until told to switch to ZAU. However, I was not able to get flight following again until rockford. I was getting flight following from rockford until about 15-20 mins before encountering the other aircraft. None of the flight controllers told me to climb to the correct altitude of even thousands +500 ft.
