Help a newbie 😅

I bought Gran turismo 7 recently and this is my first racing sim game. I play on ps5 and duelsense controller and not thinking of upgrading my setup for a long time. So can anyone tell me best settings for controller plus the roadmap that i can follow and enjoy. Not just be like a headless chicken 🥲.

So my current level is I couldn’t pass 4th test of license b 😂😂.

Any help is appreciated 😊
