How to practice for SQL and Python technical rounds

Hello,

I know how to code and have been using SQL for 8+ years and Python for 2 but its through googling/AI. I know what needs to be done but I always have problems with remembering the syntax.

Now for these roles that I'm applying there is someone on video watching me code which is not how I work. Are there any websites where I can practice SQL and Python timed queries? Or if anyone has any other suggestions on how to prepare then please share.
