@tokhir929431 My email is from LSAC. It's under the first section "LSAT Test Dates." I also received an email yesterday from LSAC titled "Update on how and when to schedule your upcoming September 2022 LSAT." Hope this helped :)

I have an email that says scheduling opens on Thursday, August 25. The email is titled "Important Information about the September 2022 LSAT."
