<p>My son is in 230 right now (it’s a full yr course). He took BC calc, multivariable & linear alg while in HS. But he had not done any proof based work, so 230 was like an entirely new universe to him. It’s a ton of work - like 20 hrs/wk at least, but he absolutely loves it. He might major in math &/or econ and would not even consider dropping the course because, as he told us, he would never have the opportunity to learn this math in any of the regular math courses. If you are a prospective math major and/or really love math and want to learn serious math, then consider 230. It is not for everyone.</p>
