well, i mean, if you're "stuck"(hard to believe tbh), why not?
can you use a site like csgostats.gg and track your profile, then can I check it? I want to see your comp games, curious
also play brutalCS FFA DM to practice aim, it helps a lot, i'm 5000 (points? ELO?) on there, gives a good perspective on how good your aim is
