Agility- When you start off, go to the circus place. Jump around there and level your agility to 2. From there just jump on top of buildings where the gang leaders are and you'll get 4.
Strength-Go around punching stuff. Easiest 4 stars.
Driving- When you first start off, instead of picking one of the 3 agency vehicles take the cop car. Go really fast out of gate 1 and you will go off the ramp near the purple gate, that is your first 60 pts towards 1 star. Then just run over people.
Fire arms- Shoot people. Aim for the chest at low levels as you will miss when aiming for their head. Don't get to close or you will smack them with your gun and you will get strength orbs.
Explosives- Go to where the one gang leader is at the sports place, behind there you will find him near the beach. Kill him and take his rocket launcher, get near about 3 gang cars and start wrecking havoc until you're out of ammo. Then just go to a supply point and reload.
Final advice- When climbing the agency watch tower, don't fall off
