<p>According to the university, BA and BS is pretty much the same thing. BA just puts more emphasis in humanities and arts (and thus some required courses are geared toward that, like foreign languages). BS gears toward mathematics and physics (and required courses are geared toward that).</p>
<p>I know when some employers put out listing, they usually accept both BA and BS jobs if they are related. So there is no clear difference.
But for salaries, I honestly don’t know. I am a grad student at Cal (so I currently have a BS degree, working my way towards Master’s). I earn about $78,000 as a Software Engineer. My friend has a BA degree and currently earns about $81,000 as Senior Software Engineer. But before he earns about some 60k for the same position as me (Software Engineer).</p>
