Depends on their condition. If you have a bunch of practice tests that aren't actually written on, I think they'd sell easily. I'd even been interested in any newer tests that aren't all written up!
what do you do with your BR once you have written out all your explanations? I haven't begun PTing yet, but I'm curious if you keep a log of all your BR PT's and review those or if you only BR once and hope you learned your lesson from individual BR.
During the written section, I'll let it slide (since I can write well with distractions). For any other section, I'll ask the proctor if they have a tranquilizer gun.
@yimei I don't record the webinars, but all the content—aside from the questions I answer at the end—is available in the Admissions Starter course. Just scroll to the bottom of the syllabus for videos and written lessons about personal statements.
