35 for tier 1st , and for tier 2nd & 3rd try to score as much as possible try to score 65+ in 2nd & 3rd tier
IB never released there cut off.
the expected cutoff is 68, as stated on web
safe zone : 65 marks minimum
They had never OFFICIALLY revealed cutoffs before but if you get marks in between 50-60 (General Category),then you can stand a chance.
for generals it's safe to have a 65+
IB never released there cut off yet.
