<p>Well, you don’t need to be a genius, but, honestly, either take 140-141 or skip to 222 altogether. If you are smart and have no real knowledge of calculus then you can take 150-151. Or, if you wish to take those 2 courses, try to forget all the previous calculus you’ve learned. Really. Because otherwise you’ll feel like you’re wasting your time at first, though in many cases, it really isn’t a waste of time, as a number of students just didn’t learn calculus properly and don’t actually understand it (though they have memorized a number of basic formulae), so they get burned from the midterm onwards.</p>
