I had the same issue during my last LSAT. I ended up taking it on my parent's laptop. The extension would download but proctoru never worked on my laptop for the LSAT. If possible, I would go to a local library to take it, your school, or use a family/friend's desktop for the test.

Hi, I took the LSAT in April and September. The April LSAT for me went reatively smoothly aside from the system crashing for an hour. My September LSAT was hard mentally. My Proctor during the September LSAT also kept telling me to sit back in my chair and this made my anxiety go up and I lost focus. I have vision issues so I have to be closer to the screen. I would just make sure you are in a quiet room and always sit in the view of your camera so that they don't check in on you during your test. When they checked in on me, they blanked out my screen and told me to sit back without pausing my time. I ended up losing about two minutes of time on my logical reasoning section because of this. Best wishes on the October test!

Good luck,

Maggi :)
