For the common app prompt #3 about questioning a belief, I wanted to write about how I questioned Christianity, but is this acceptable and not cliche? I hope it seems like a fitting topic and doesn’t seem cliche
if you are genuine and can express this in a essay in a way that is uniquely “you”, then by all means go for it
It’s not unique-- but so few topics are.
But write a draft and see what you think. Be sure, of course, not to offend any reader who might be Christian.
