No, unless you complete some subjects in IB1. E.g, at my school, we finish math SL and French B SL at the end of grade 11 and finish the other 4 subjects at the end of grade 12. So in that case, the results of our math and French exams count as our final IB mark for those subjects.
I live in Ontario and only applied to Ontario universities, they didn't look at my IB marks (predicted or final) at all. If you're out of province, they may look at predicteds.
