In the Singaporean context for IB, how would my chances be if I did not receive straight grade6 and 7 for year 5

From an international school, our papers are generally harder than IB ones. Received 2 grade 5s and 1 grade 4 for MYE and 3 grade 5s and 1 grade 4 for EOY. I would place my score at roughly 60/70th percentile.
