Recently went through calibration in CS2 competitive mode and it turned out to be a real challenge. I decided to share my experience to help those who want to get a decent rating from the first matches.
How I prepared:
1️⃣ Played with a team. At least 2-3 trusted teammates - already a guarantee of info and support.
2️⃣ I trained aim and grenades. Before calibration I went to DM and watched simple tactics so that I wouldn't play chaotically.
3️⃣ Explored alternative ways. If you don't want to take risks, there are services like GoRanked.gg https://goranked.gg/en/cs2/boosts/competitive-calibration where you can order help with calibration.
