Advice for first time travel for F1

Hey all, first time trying to travel for an F1 race. I see tickets where released and some sites seem to say there will be more being released. I'm looking for a 2 day GA pass ( as my flights don't allow the Friday session) if possible to keep cost down but if these are unlikely to be released I'll buy a 3 day grandstand and just miss a day. Any advice here are the likely hood of more tickets being released or how it may have worked in past years would be appreciated thanks 😊
