So- I just got a letter in the mail from my alma mater (college). I have been asked to write a letter of reccomendation for a professor I had that is up for tenure. I LOVE this professor- but I have no idea what I should write about. All the letter said was 'write about his strengths, but we all have weaknesses and those should be addressed as well'.ug- don't know what to write- any thoughts please?
