What is the best online traffic school in California?

My sister got a ticket in LA and the judge said she could take traffic school to keep point off her record. She's never had to do this before and searching for online traffic schools in California brings up what feels like 50 different options.
Some cost $5 while others are $40 and she genuinely can’t tell what the difference is.

What she’s looking for DMV approved in California, provider handles reporting to the court, at least some video content (8 hours of tiny text would be brutal), same day certificate

She’s come across IMPROV, a bunch of the "$5 traffic school" sites and a few others. Has anyone taken an online traffic school in CA recently? She’s not looking for the absolute cheapest option, just one that won’t make her regret getting the ticket in the first place.
