I believe that UCD puts heavy weight on the statistics end of the application (GPA, GRE scores) in that they filter out any application that doesn't meet a cut off before they look at your PS, extracurrics, ect. However, if your GPA is their average, I'd say it's worth a shot to apply to them! Your GRE score is not that bad. They also really like re-applicants who apply a second time to their school (one of my friends got into the 2018 class after being rejected to the 2017).
In terms of improving your verbal score, the best advice I can give you to tackle the verbal section in two ways: vocab memorization and critical thinking skills. Memorize as many words as you can! I know it's difficult, but somedays I would literally just sit and go through 4-5 stacks of 50 vocab words. Also, go over words you've learned or think you know a few times because it's easy to lose it haha! For the passages, learn how to read the passages well and to take notes on your scratch if necessarily (like what is the main idea of the passage or what does each paragraph talk about). Take LOTS of TIMED practice tests, and push yourself to test your skills. The 3 weeks up to my test, I took a test everyday just so I could get a hang of what type of answers they were looking for.
Haha it was hell, but totally worth it because I ended up getting the score I wanted 🙂 Your stats look good though so just apply with a positive approach, and what is meant to happen, will happen! Best of luck xx
