HOur build and get the ME out of the way, you need to have a pass in your hand before sitting the SPA-ME-IR flight test.
Do your IR and pass it.
Then do your CPL in either an SEP or MEP your choice of 15 hours.
Then try and get your timing right so that you finish the CPL course bang on 200 hours TT then sit your CPL test. Factor in a hour build of 5 hours or so to get your hours up at the end and you can either then use it for additional training or go practise a nav-x by yourself.
Also find out if the school requires a separate 170A flight check for the CPL. You don't actually need it but some will make you do it anyway. And make sure you have factored it in when computing your 200 hours.
