Functional Skills changed in September 2019 - this included some significant reforms (please see link below).
There was new content added for both English and maths.

Dictionaries and spell checks are no longer allowed on written papers (at all levels).  Also, for the first time, there is now a calculator and a non-calculator paper (at all levels).  

This split is 75% / 25% (as decided by Ofqual).  

Functional Skills English Level 2 and maths Level 2 Information can be found here.
