Are English Lang exam boards mark schemes the same?

I've found that there are very little resource materials for people sitting the WJEC board English language compared to those sitting the AQA. In particular all i'm looking for is how to answer different styles of questions, would i be able to use the advice from youtubers etc who say it's for AQA to help me answer WJEC questions or would the wjec mark scheme be very different to that of AQA?

Mark schemes can be different, but cross-check before using it
