Health is the same for all classes across all factions; 500 shield (400 for infiltrators, a good infi doesn't get shot in the first place), 500 HP and MAXs have 2000 HP with no shields.

Exp on the other hand is more fluid. Below your map is a bit that shows you a percentage, (If playing on a PS4 skip this bit) hitting ALT will let you hover a mouse pointer over it to see whats making up the parts of that percentage, if any. Any exp you get will be increased by this amount, the fall list of which is probably somewhere on this wiki. The easyest to look out for is simply the more the enemy out numbers your faction on the map as a hole the more exp you get.
