Hasn't been said yet but use all available resources as well. Generally you'll be going to an airfield that is a CTAF, generally on 126.7, there are a lot of aerodromes that operate on it and some will be close to where you are going. If you hear
"ABC departs 'The airfield you want to go to' at time...blah blah blah" Check their rego and give them a call and ask them what the cloud is like there!
Has gotten me out of trouble before, heading towards an aerodrome with no AWIS and your a bit unsure listen to the other traffic in the area and ask for some help if you need it "ABC, DEF, enroute to "the airfield" can you tell me what the cloud base is there?"
Sometimes you'll find out its a lot lower than you expect or a lot higher, sometimes you'll get a real friendly response "Yeah, just came from your direction, gets a little low over the ranges but clears up nicely on the otherside" or "Just came from there, IFR...your IFR right? Your gonna need to be..."
Good luck with your test, remember good command decisions, use all the resources available to you appropriately, don't go over the top though!!
