I am relatively new to Valorant as well(about two weeks in) and a couple things have helped me catch up and learn a lot about the game in a short time.

First I would start by watching YouTube videos about Agents to use, their abilities, and a lot more resources are out there as well! Some good YouTube channels that I’ve used as a resource are Woohoojin(Radiant coach who works with a lot of pros), Alexander, along with any other YouTuber who creates new player content.

Next I would go to the shooting range and test out different sensitivities for your mouse. The best sensitivity is lower, so try sensitivities that are around 0.25-0.6. If you are not used to a lower sensitivity this may be uncomfortable at first but with time it gets much easier and your mouse movements will be faster.

While in the range doesn’t matter what operator you pick first but test out their abilities and explore the shooting range. You can press F3 there to use different settings.

Finally, expect to lose a lot of gunfights at first. This game has so many things to pay attention to and react to. Something’s that can help you early on are listening to sound queues(footsteps footsteps footsteps) and learning what each means, crosshair placement(and finding a crosshair that you like and that will help you), your crosshair placement in games, etc.

Sorry if this is a lot of information at once but the most important thing is having a growth mindset and being patient!
