<p>I didn’t take physics in high school and Calc level physics was not hard at all. Just make sure you stay on top of your work, focus and study smart. It’s all about understanding the concepts. Concepts in mechanics are very starightforward and logical to understand.</p>
<p>But I guess it depends on the person.</p>
<p>Khanacademy.org. Is an excellent site to help you with physics.</p>
<p>Where you may have problems will be physics II. In Physics II you study phenomonon at a quantum level such as electromagnetism so it is difficult to conceptualize and you have to kinda trust what your learning is actually that way.</p>
