4200 isn't too bad. Its the same flight five times in a row. If you know your procedures/EPs and can recite them verbally without hesitation you should be golden if you're not Mongo with the stick.
Spend the time early on in Primary learning everything, at the expense of going out if need be. It'll save you a lot of stress on the back end and you'll have much more time to relax/go out then.
