For new drivers , you can make appointment online for write and I think for driving test too.Call customer service,they give will give better infomacion and fill up the application in the web side of DMV.
Check the DMV.CA.GOV site to see what the current rules are. They can change as the pandemic effects change. I would strongly suggest you download the drivers manual, read it, and do the practice tests so you don't waste a trip.
