<p>English is too important to drop. At the very least, any respectable college will want to see four years of it. Even if you have absolutely no appreciation for literature, the reading and writing skills that you’ll pick up over time will come in handy. I might drop psychology or statistics first. </p>
<p>What went wrong with pre-calc? Did you find the material difficult, did you not study it enough, or did you simply do poorly on tests? Or are you sometimes easily stressed? Most college engineering programs are very intense and stressful. If you want to apply as an engineering major, you need to make sure you are comfortable enough with math and physics to get through it. I think you should get private tutoring if you can afford it. </p>
<p>Sometimes in calculus it is very helpful to look for a physical or graphical interpretation of concepts. Try to get someone to explain things to you using pictures instead of just equations. If you’re having trouble solving problems, try to go back to first principles and see if you can work out a solution.</p>
