Hello, I wondering if these grades were good enough to participate in top grad schools. I have a few A-'s that I am worried about. Also, what is the difference between a 3.95 gpa and a 4.0 in the eyes of the graduate school committee?

Math

Calc 1 (Took it in high school. AP)

Calc 2 A

calc 3 A

ODE A-

Linear A- (I had a bad summer which contributed to this. A 94+ was an A which is silly.)

PDE 1 B+ (Same summer. My mother accidentally signed a lease for a second apartment which added a lot of struggle. Affected my grades)

PDE 2 A

Advanced Linear Algebra A

Math Stat/ Probability A

Complex Analysis A

Intro to Abstact Algebra A

Intro to Advanced Math A

Topology A

Real Analysis A

Physics

Gen Physics A - A

Gen Physics B - A

Modern Physics - A

Mathematical Physics- A

Intro to Astrophysics - A-

Astrophysics Lab B+ (One credit course)

Physics of Stars - A

Mechanics 1 - A

Mechanics 2 - A

Quantum 1 - A

Quantum 2 - A-

E&M 1 - A

E&M 2 - A

Thermal Physics - A

General Relativity - A

Cosmology - A

Nuclear and Particle Physics - A

(Grad Course) Theoretical Dynamics - A

(Grad Course) Statistical Mechanics - A

Chemistry

General Chemistry - A

Chem Lab - B+

(One credit course)

These are my grades. Now what I am concerned is how these A- grades will be interpreted by the committee. I don't think my A- in Intro to Astrophysics will matter as that is an intro course (We didn't even use calculus for god sake). However, I am worried how my other A-'s will look like. I will be applying for theoretical cosmology/astrophysics, so I don't think my lab grades will matter. My math gpa is about a 3.92 and my physics gpa is roughly about a 3.95. I know theory is highly competitive, but how does an A- look in the committee's eyes?
