Don't apologise! Happy to help!
It may vary from firm to firm but yes, SQE courses generally start in September.
An example of my ULaw timeline:
September 2024 - SQE 1&2 course started.
August 2025 - classes ended, some coursework still ongoing.
September 2025 - generally hand-ins complete. September 2025 cohort trainees start their TC.
October 2025 - SQE course officially ends.
March 2026 - March 2026 cohort trainees (if applicable) start their TC.
As most firms begin their TCs in September, I imagine this timeline will be the same/similar for most firms, though it would look different if the applicant needed to do the PGDL.
