I would think the adcomms won't go into so much detail with who exactly the professor is, just as long as it's stated in the LOR. @david.busis will have a better response.
Thanks for your response Jonathan, my question was about PT35.S1.Q18. I think a mod edited my post when I originally posted it, and put int he wrong question. I've just seen it and changed it back.
Hmm this can vary greatly on the question type and so my response would be much too long in order to nail down the numerous reasons why one couldn't identify an assumption. Do you have a specific PT question number I can use as a reference?
