<p>My son has a professor that went beyond the rec and has been very helpful to him. The professor has written recs for scholarships but not his grad schools yet. He wants to write an email/type a note when everything is done to thank the professor for going beyond the usual. He has to type it because his handwriting is atrocious but I think a heartfelt note is worth more than any token gift. Everyone likes to be appreciated and a note lasts a long time and can be read over, hopefully with a smile.</p>
