At the beginning of the year, I asked my form tutor to fill out a bunch of references for work experience, and even though he was disgruntled, he did it. The reference was not that good in my opinion but I didn't want to waste more time and I sent the application off.
A couple of weeks ago I asked my form tutor to fill in yet another reference for Nuffield Research placements, however, even though he said he's always happy to help, he seemed like he really didn't want to do it. Now, everytime I talk to him he doesn't acknowledge me and has no eye contact. I really can't ask him to write another reference for me but I have no other teacher to turn to. The placement is mostly a backup but it is still important.
Should I tell him to write me another reference or just not apply?
