BMI calculated was wrong by Cambridge!

[chele]

I saw my counsellor on Wednesday and she said my BMI was 41.

According to other websites on here it's 38.5

Is the Cambridge way of calculating BMI incorrect?

I'm 5' 6.5" and 17 stone 3 on her scales.

Hmmm so 41 was def wrong. Shall I say something to her?
