Practice is very important. It is important to develop good form and be sure you stay consistent with that form. If you keep changing your shot technique, it will be difficult to become a better shooter. So, find a shooting technique that you are comfortable with and PRACTICE! PRACTICE! PRACTICE! Good Luck!
You should practice and also watch some videos on good shooters that will also help you by looking at the viedo's you can watch and see where on the basketball court you can soot to get your precentge up
Like all have said - *Practice* is very important. Practice from all angles and work on your shot form. Also, don't forget to use that backboard! I see too many players trying to make "swish" shots. They are pretty but playing near the basket, getting square and using the backboard will greatly improve your shot percentage.
Use B.E.E.F. Balance, Eyes on Target, Elbow, & Follow Through. Another one that I learned this summer is get yourself under the basket and make sure your elbow is even with your nose in the form shooting style and then flip the ball off your fingertips into the basket. It takes some practice but it really works on your form. Do about 15-25 of these before shooting from any range. I have my players start with this drill and then start shooting close to the basket and then after make 5 in a row they can move back two or three steps and shoot again.
Yes practice on your form meaning keep your shooting elbow in to the middle of your chest and then press and release the ball from your finger tips snapping your wrist. This will give the ball good rotation. Your must practice this shooting technique as many times as you can until you feel comfortable. You will be surprised when you see your shots going in over and over.
