An amazing resource. How long do you think it will take for you to complete the whole course?

[@ALevelMathsRevision]

Thanks for the kind words. I am uploading videos as and when I teach the topics to my class so I'm hoping to have the bulk of it done by Easter.

You're welcome.

Aren’t you supposed to use the row and not the column to find the determinant?

[@ALevelMathsRevision]

You can use any row or any column. Just make sure you get the sign associated with each entry correct!
