Solo DSA grinding stalled for months, a weekly study group is what actually got me moving again

Six months of solo LeetCode and I'd basically plateaued, doing problems without really absorbing why a pattern worked. Joined a small weekly group, three other people, where we each explain our approach out loud before showing code. Having to actually articulate the reasoning to someone else exposed how many gaps I'd been papering over by just checking the solution when stuck. Slower per-problem, but it's stuck way better than anything I did alone.
