Becauss I am just stuck at one level
Hey, I don't know at what level are you now, but let me help you. My wife bought her first PC half year ago and she never played any FPS games on PC, but with my coaching, she has reached platinum. So as you can see, I am very experienced coach, im just waiting for the 100T coach invitation (KEKW)
Most of the people here will tell you to just go practice your aim in aimlab or smthn like that, but I would recommend you to study Valorant logic first, because smart > mechanical (at low level atleast). The best thing is probably to get a friend, who is already high rank and won't have a problem to play with you, just to coach you. But you definetly need to understand, that every agent has its role. As a "individual smartness" (idk how to call it) its again just the best to get a friend, who can analyze your clutches and plays. Even watching pros will definetly benefit you, although I recommend to watch them streaming ranked games rather than playing PRO games at some tournament.
After receiving bit of knowledge of the game, I would recommend to study aim technics such as jiggle peeking, good crosshair placement and working on your muscle memory in aiming. Watch this video: https://youtu.be/7jtDGa59Mkw It's very well made for things like this.
What is also really important are comms. In silver/gold and lower ranks, people are just constantly flaming and screaming. Just mute them, play your game and give comms. These things can get into your head and can really affect your gameplay.
But as I said, the best thing is definetly to get a high elo friend to help you improve your game decisions.
