I had 60 min at the beginning but it was not enough... With previous T I had 2 x 50 min and it was even worse... Now I have 1 x 90 min and it is perfect for me... I have the feeling that in 90 min I can say much more... With 60 min I needed 20 min to think what to talk about, conclude the previous session and discuss the e-mails, then I was talking for 20 min, then my T was talking a bit and then I was feeling that it wasn't worth anymore to start a new topic because the time was almost up... It was pretty frustrating... 90 minworks for me... Maybe your T could give you some more time when you need it?
