As noted above, good for what? Compared to what?
AP_Trevor has, or soon will, post the score distributions for each test, if you’re looking to see how they compare against other students taking the test.
The tests you list generally have 15-20% 5’s, with the next 20-25% scoring 4s. With the exception of BC - it’s not posted yet, but it historically has 40-50% students with a 5.
