Start from the blue then the wolf; now a gank then wraiths and golem; now another gank; now kill the red and clear the jungle. Don't forget to use the smite also on the "minor" creeps like wraith or golem. Use ur Q to maximaze the damage. Don't use the E.

It's very easy. Do you have ulti?

• YES: Use the ulti to jump on the enemy, then E, then W (so u can't be blocked by CC), then Q and beat the **** out of him. Recap: R-E-W-Q
• NO: Hit the enemy with Q, then E and W. And beat the **** out of him. Recap: Q-E-W

My advice is to use the smart cast.
