Stony Brook. Would i get in?

I'm only a sophomore right now; so i know it's kind of too early to tell, but can you tell me if i'm headed on the right path...

I want to major in chemistry at Stony Brook, but last year my grades were really rough... this year though, they've gone up.

Here are my grades:

HONORS Global- 77. :[

Biology- 78. :[

HONORS english. 82. =/

Integrated Algebra- 88.

gym- i cant remember...

band- cant remember

Spanish 2.. i cant remember either...

Overall average- 84. :/

THIS year (so far)

Chemistry- 90.

Geometry- 90.

CP English- 93.

CP Global 10- 99.

Spanish 3- 96.

band- 96.

gym- 97.

overall average so far- 94.

Right now my guidance counselor said my gpa is an 89.. I know its not amazing, but i'm really working on improving my grade... So far, this quarter al my grades are 96's and above... so i'm hoping to higher it up.

Other things to know-

I'm in our high school's marching band (and concert band)

I've been in STEP club since 7th grade. (Science Technology Entry Program)

This year I joined robotics club.

I haven't taken any SATs, so i can't tell you those, but im hoping i'll do good...Any idea of what score i should be aiming for?

Also, another question...

I have the option to attend summer school to replace my old grades that weren't too good.

Should I?

I'm about 99.9% sure i'm going to take biology, but i'm wondering if i should retake english 9 and global 9.

My teacher said that since it was honors, i shouldn't retake them, but its bringing down my gpa... so should i?

btw, i plan on taking these classes for the next 2 years:

JUNIOR YEAR-

1. Algebra 2/Trig

2. Physics

3. Honors U.S History

4. Honors English 11.

5. Psychology
