Can you drive by yourself with a provisional drivers license to school or for sports activities?

No. The laws in California state this:

After you pass your driving test, you will be issued a provisional driver license. With your provisional driver license, you must be accompanied and supervised by a licensed parent, guardian or other licensed driver 25 years of age or older, or by a licensed or certified driving instructor when you:

• Transport passengers under 20 years of age at any time, for the first twelve months.
• Drive between 11 pm and 5 am for the first twelve months.

This means you cannot give anyone under 20 years old (your friends, your brother(s), sister(s), cousin(s), etc.) a ride unless you have a licensed parent, a guardian or other adult 25 years old or older in the car with you. You are also not allowed to drive between 11 pm and 5 am during your first year after getting your license unless you have a licensed parent, a guardian or other adult 25 years old or older in the car with you.

With a provisional license, you can drive by yourself between the hours of 5 am and 11 pm. If you are under 18, you cannot be employed to drive a motor vehicle.
