<p>Whether you major in Physics or Astronomy you will be taking pretty much the same courses either way.</p>
<p>For Physics or Astronomy you have a lot of catching up to do in Math if you are only taking Algebra now. I am unsure what "Technical Math"is but it sounds like a vocational course in Math. You need to take Pre-Calculus so you can started as soon as possible on a three semester series in Calculus that includes Multi-variable Calculus. These courses are the fundamental background you will need to succeed in your Physics and Astronomy courses.</p>
