Is a 31 on the ACT a good score?
Is it good enough for UCLA?
Yes. A 31 is good enough for UCLA, but you also need good grades and some activities.
UCLA gets a ton of applications - almost 100,000. How will you stand out?
As stated above, an ACT score of 31 is within range for UCLA, but UCLA like the majority of UC’s are very GPA focused so you need a competitive UC GPA, interesting EC’s and great essays to get that acceptance.
