Picking Senior classes?!?/Career choice

In a few weeks we are going to finalize our classes for senior year and I’m preety torn.

For the past few years I’ve been really sure that I want to major in Political Science and eventually go somewhere in government. However upon doing some research I see that it might be a risky career path with job stability and outlook. So now I’m looking at a completely different major and field, Materials Engineering.

So I just want to know what’s the best path to go with and the best classes to go along with them.

This is what I was thinking
Political Science

  • AP Gov
  • AP Euro
  • AP Psych

Engineering

  • AP Physics C
  • PLTW Intro to engineering (is it to late to take this as a senior???)

Thanks for the help!
