You are far more likely to receive credit for a 4 than not. A 4 isn’t perfect, but it’s still above average. It’s like if you worry about a B, it’s still above average although some treat it like it’s a C or D. A 4 according to college board is about an A- or a B+ I’m pretty sure, so it’s still above average. You definitely didn’t fail if that’s what you’re worried about.
