Anyone remembers CEM 2020 11+ dates?

Are there any posters who would know the date of the last exam (2020 entry 2021) not the one coming this September for any of the following schools? Or roughly the month? Basically I want to know if they all sat it at the same day as they were meant to share it.

Gloucestershire Grammars
Slough Consortium
Reading School
Kendrick School
Chelmsford County High School
Heckmondwike Grammar School
Bacup and Rawtenstall Grammar School
Queen Elizabeth Grammar School Penrith
Trafford CEM Consortium

Thanks!

Trafford consortium CEM test was on 19th October. It was delayed by about a month due to COVID

Heckmondwike was also 19th October, delayed from 16th September.

Thank you!
