SAT with essay

I took the SAT with essay and got a 22/24 (8 reading, 6 analysis, 8 writing) and I’m taking the test again in March. Is another essay worth it? I feel like my writing has definitely improved since I started AP Lang but I’m happy with my score and I’m scared I may do worse somehow if I do it again. Then again, I’m looking at some top schools like JHU, UPenn and Princeton, and it’s always nice to (try to) do better than you have done before.
