Easy Early Lvl for Archery and Sneak
This works for all levels but most effectively in the beginning. Go southwest of Whiterun (almost at the end of the divot in the mountains) to Secunda's Kiss. Coming from Whiterun you will see a trail. Go just past the first stone marker and then go right. You find that you can shimmy along the edge until you are on an overhang. There are two giants nearby. Set the difficulty to Master so they are harder to kill; then go to sneak mode and go at it with your bow. Shoot them once ONLY every time the eye moves, this way you don't kill them. When their health is low, leave and do your thing and then come back to them (after a good while) to full health. Repeat and reap the rewards.
