I dropped a class and only have 9 units now, will I still have health insurance?

I'm on my parents health insurance plan which is Anthem Blue Cross. I dropped the class September 16th thinking that I would be covered till 26 without being enrolled in full time units. But I read that the being covered till 26 just kicked in september 23rd. So will I still be covered by health insurance?

Unless the insurance company finds out you dropped that class, you'll stay covered. You should have waited until Sept 24th to drop.
