<p>I have a somewhat similar story, in that I flunked out of high school, always hated math and science, and years later developed an amateur’s interest in physics, and long story short I’m an engineering physics major now.</p>
<p>I spent all of 2009 studying math at home and during spare time at work, beginning at the ACT prep level (basic high school algebra and very very basic trig), then moving onto pre-calculus, then onto differential then integral calculus. I did this all with books designed for the home learner. By the beginning of 2010 I was in college and with one exception (vector analysis, where I got an A- due to a BRUTAL final exam) I got A’s in all of my math classes. Right now I’m in an error analysis class and struggling to fully understand all of the concepts, but I’m hoping that like the dot product and cross product, it’ll all become second nature.</p>
<p>So my advice is to find the level of math you need to start at because you need to have mad, 1334 algebra skillz to do well in college-level calculus and physics. Calculus is easy, the concepts are quite simple, it’s the algebra involved that trips people up, especially in integral calculus. Differential calculus is so easy because essentially you just have to follow the formulae and you’re done, integral calculus is where you have to do all of the algebra and that’s where people often hit the wall.</p>
<p>My second piece of advice is to take a computer programming class in a language like C or C++. A <em>real</em> programming class in a <em>real</em> programming language, because the concepts I learned from studying C actually bolstered my algebra skills quite a bit by training me to think in terms of functions.</p>
<p>My third piece of advice is to take a basic, high-school level physics class to understand the concepts. In fact, here are some books on that subject:</p>
<p>[Amazon.com:</a> Conceptual Physics Package Edition (9780805391909): Paul G. Hewitt: Books](<a href=“http://www.amazon.com/Conceptual-Physics-Package-Edition-Hewitt/dp/0805391908]Amazon.com:”>http://www.amazon.com/Conceptual-Physics-Package-Edition-Hewitt/dp/0805391908)
[Amazon.com:</a> The Physics of Everyday Phenomena: A Conceptual Introduction to Physics (9780072828627): W. Thomas Griffith: Books](<a href=“http://www.amazon.com/The-Physics-Everyday-Phenomena-Introduction/dp/0072828625/ref=sr_1_3?s=books&ie=UTF8&qid=1335399098&sr=1-3]Amazon.com:”>http://www.amazon.com/The-Physics-Everyday-Phenomena-Introduction/dp/0072828625/ref=sr_1_3?s=books&ie=UTF8&qid=1335399098&sr=1-3)</p>
<p>And my fourth piece of advice follows the second, it is to read books of physics brain-teasers:</p>
<p>[Amazon.com:</a> Mad About Physics: Braintwisters, Paradoxes, and Curiosities (9780471569619): Christopher Jargodzki, Franklin Potter: Books](<a href=“http://www.amazon.com/Mad-About-Physics-Braintwisters-Curiosities/dp/0471569615/ref=sr_1_6?s=books&ie=UTF8&qid=1335399167&sr=1-6]Amazon.com:”>http://www.amazon.com/Mad-About-Physics-Braintwisters-Curiosities/dp/0471569615/ref=sr_1_6?s=books&ie=UTF8&qid=1335399167&sr=1-6)</p>
<p>Among others… These brainteasers really help build up you understanding of the concepts. I’ve seen many other classmates struggle with material because they didn’t have the fundamental concepts under their belt, they had learned the material at too high a level, too mathematically, so when posed a problem that went beyond the formula (which they understood), they didn’t know what to do.</p>
