advice for competitive

any advice for a silver 1 that want to improve in competitive? I already do some 1v1 once a day just for aim training, what can I do more? I'd want to try retake servers but idk

First, you need to understand the basics of CSGO, if you think you are ready for MM and believe you are good enough to rank up, you can start playing.
Don't play solo, most of solo playing are made by fraggers and KDA players, you will get jebaited a lot, and people will simply die trying to frag. With a full premade with the same menatlity, can grow together an rank up quicker.
If you want to take it up a notch, maybe you want to start playing with a premade with higher ranks if you are feeling confident, its easier to rank up that way, becasu MM fixes your elo accordingly, getting you more elo than the average games playing in your rank. Its a double edged sword becasue as it gives you a boost in your grind to rank up, it gives your teammates a penalty making it easier to derank and really ahrd to rank up.
I already won games and deranked and i already ranked up in a win/tie.
Play a lot of Deathmatch and FFA to get your aim and reaction on point, always warmup for like 15, 30min before playing and if you want to go the extra mile, play FFA Only headshots for that crisp clean taps. Play with Deagle to see if your aim is on point since its a really skilled weapon, play AWP to train your reflex and flicks and play m4 for spray controls and ak for taps.

Mouse cursor placement is essential for improving accuracy with faster reaction times, preemptively placing the crosshair at head height or where you expect the enemy to be before they peak reduces the distance your mouse has to travel before firing. Comfortable hardware such as a well-calibrated gaming mouse or a +120 Hz monitor can also improve reaction times. Mechanical skill aside, improving game sense is sometimes an understated consideration that can make a dramatic difference for overall performance by paying attention to things like common player paths for prediciting enemy movement, listening carefully to footsteps and audio positioning, effectively using smoke gernades for cover, knowing how to rush a point with your teammates and which angles to cover, rotating at the right moments, and anything else that can improve your chances for success in terms of strategy. Most of these principles will become obvious with continuous play and experience.
