1. Keep track of the distance between you and the hoop
2. Tuck your elbows inward towards each other when shooting
3. Shoot the basketball at an arc. It increases accuracy
4. Aim at the part inside the rim farthest from your standpoint
5. Use screens and offensive-plays to get open
6. Square up your shooting hand with the basketball hoop
7. Grip the basketball tightly with only your thumb and little finger
8. Aim with your index finger or middle finger only
9. Never hesitate due to the fear of a block shot.
Hope it helps.
