Hey.
No I didnt get an email but if I got to reference it says I cant send a reminder for 14 days so I know it has been sent for the reference request. It wont be until tomorrow now though as my Uni Professor wont check her emails.
As for the question above, I would recommend asking your uni lecturer for the reference. It would look a bit suspicious if you didnt, as you are at Uni not sixth form anymore. The academic reference is in relation to your academic abilities and your skills that would allow you to teach, it isnt personal. Thats why you have a second reference, I would recommend you put your sixth form teacher as secondary reference or the name of someone where you have gained experience.
