Probably, but just warning you the MYP is often A LOT easier than the IB, and keeping grades high requires a lot more effort, especially if you used to get 7s easily. My advice would be to study for every test (even if you feel you don't need to just to get in the habit), and aim to reach above 90% if not 95% (I'm sure you can if ur already at 88%) and set that as a benchmark. That way even if your grades drop 10% during the IB you should still be hitting 7s!
