Need some advice about revision for a levels

Hi guys, this might seem like a stupid question but I’m not sure whether to start revising year 1 content or get done with making my year 2 resources so i can revise it all and not worry about making flash cards etc.

i definitely should have done this earlier but i can’t go back in time, and atp im just procrastinating because i feel like it’s taking up so much of my time since im just making my flash cards for year 2 content when i could instead be going through all my year 1 content.

Any advice appreciated thanks guys
