Political science is impacted, but as @cheolf said, you’ve nothing to prove by taking calc 2. UCLA won’t care if you take that class.
You’ll most likely still get in at UCLA with a 3.87 GPA, higher than the average for that major. Berkeley as well.
I haven’t been wrong(to my knowledge) about predicting who’ll get in and who doesn’t yet, and I’ve been here a while.
