Thank you for responding.
If you're undergard was in the UK, I guess the medium of instruction would have been english. In such a case, I think you do not even have to submit an english proficiency test score.
My under graduation was in India and Masters was in UK. HBS specifies that when UG is in a english medium university and Masters in a english speaking country then "it is advised to submit the English score"
I agree that if they mention Toefl ibt score 109 and Ielts score 7.5 as cut off then applying with a Ielts score of 8 is better, but does it hurt to share the Toefl ibt score of 108
If you found the reply to be helpful, give kudos.
