So freshmen year I got a 3.8 GPA with 2 Bs in English and 1 B in math. I’m currently a sophmore and my first semester I got 2.8-3.0 what are my chances I can still go to a good college? Namely University of Washington or similar ranked school. I know for the rest of high school I can increase my GPA a lot. I really got distracted first semester and am working to change. I currently attend a top rated California high school with 2 parents with PhDs so a lot is expected of me. Should I consider a transfer to Seattle next to UW? What would you suggest?
You are a sophomore. See how your grades and test scores sort out junior year. Also, I live in WA, and it would be silly to pay huge OOS tuition for UW while you have a very solid in state system in CA.
Unless you like it more and are willing to pay the $15-22K/year tuition difference* (like thousands of Californians do).

Average unweighted GPA for enrolled freshmen at UW in 2018 was 3.8, so definitely keep your grades up (which will benefit you wherever you apply).
Good luck!
Most universities understand that high school students are human. If you can pull your grades up for the rest of high school you should be able to get accepted to very good universities even with one bad semester.
Moving to Washington is not likely to get you in-state status unless your parents also move to Washington. Given how hard UW is to get into, and how strong the in-state public universities are in California, this seems unlikely to be practical.
I think that you should work hard to pull up your GPA, and be aware that you have many great in-state schools to choose from.
Cumilative gpa is what matters
My sophomore GPA was a lot lower than yours… It was a 3.1Weighted, if it’s unweighted, it would have been significantly lower(around a 2.8).
Still managed to get in Michigan(Not In-state), and my Early Decision Choice(A top 20 Liberal Arts College)
So I guess you still have a chance, but need to work your ass off in all other aspects of the application to get a decent shot.
What classes are you taking?
What are you interested in?
Why UW?
By “Seattle” do you mean “USeattle”? (The private university)?
Most important: what can your parents afford? Do they have a college fund for you or if they’re academics a Tuition Exchange?
Budget Trump’s everything.
I’m taking precalc AP chem and regular other classes. I got a C in AP chem 1st semester should I drop it? I don’t think I could get a b or score high on the AP test. I’m very fortunate that tuition is not the issue and my family is considering moving to Washington for the rest of high school. (Junior Senior years) What do you suggest?
I’m interested in Business/Finance or Aviation related majors
Had you taken Chemistry before AP Chem? Because it’s a Level 2 science class, if you never took Level 1 no wonder you’re struggling - switching to Chemistry Honors would make sense then. If you took Chemistry Honors last year then try to stick it out and stay at C or higher.
Make sure that junior or senior year you take Physics (even regular is fine), Calculus if you can ( both will be expected from a STEM major), Foreign Language through Level 3,and as many AP Social Science/History classes as you can (will be expected for Business/Economics). DECA can be a good idea.
Ok, that makes sense wrt UWashington! Moving at the end of your sophomore year would likely be the safest. To get instate tuition your family would need to move no later than July after junior year. (But this would be harder on you socially and academically than moving at the end of Sophomore year. I understand that there may not be a choice).
UWashington is super selective so I don’t think you’d be competitive for it with a 2.8, but this isn’t your cumulative GPA, so you can still bring it up. One semester at 2.8 won’t permanently keep you from being admitted, but you need A/A- in all your classes beside AP Chem.
With a 3.2-3.6, you’d definitely have a shot (50-50) at WWU and Washington State.
Think of USeattle, UPuget Sound, but also UOregon, Oregon State, Lewis&Clark, Whitman, Pacific Lutheran, Montana State, UNebraska Lincoln, UWyoming… Look into those.
The State of Washington has a program called Running Start, which you could take part in - it’s like Dual Enrollment at a Community College.
The best skills you can learn in high school is time management, and learning how to study effectively. College courses are going to be a lot harder than your high school classes.
You still have junior and senior year grades to earn. Those will be most important as they will reflect your ability to handle college level work. An upward trend in your gpa would be helpful in trying to reach your goal.
