Where should I apply?

I am in 11th grade of IB diploma programme. The first semester of this year i did poorly (24 points) but I am planning to increase to at least 30 points this and next semester, so my predicted grade will probably be 30. My freshman and sophomore years were much better (around 3.5-3.8 gpa).

IB subjects:
ECON HL
MATH HL
PHYS HL
HIST HL
FRENCH SL
ENG LIT SL

SAT:
1st time 1090
2nd time 1480

Extracuriculars:

won 1st place in tennis championship (16-18 year olds) this year (between multiple schools)

my school team won 2nd place in soccer

community service:

helping people against the snow
giving out red cross flyers and asking people to donate
volunteering in organizing a track and field competition
cleaning up a park
math week volunteering
book week volunteering

Work experience:

Conclusion:
Do you think admission officers will mind a poor semester even though my other grades very pretty good?
ALso, what do u think i should do to increase my chances into getting into a university in usa
I will also probably be the class president next year
other than that do you think that the tennis champisnhip and internhsip considred as leadership roles?

FInally what universities do you think i will have a good chance at getting in?

Thank you
