Time short on thesis defense preperation
Call together your graduate school friends, and set aside a two hour block of time.
Give them the presentation in its current form.
Receive (possibly scathing) feedback and take good notes.
Go fix the presentation.
If your friends are up for it, repeat the process, but not more than once.
Practice at least two more times before tomorrow.
Give the defense tomorrow, and pass.


Good luck!
