<p>I haven’t had all of those classes, but I can say that for government, the flashcards actually helped me a lot, and that might be good preparation for next year if you decided to memorize some over the summer.</p>
<p>For calculus, if you want to prepare, it might be a good idea to make sure you know all of the concepts from pre-cal thoroughly and get a review book like the Princeton Review and maybe begin the first few chapters of that. </p>
<p>All you pretty much can do for English is read. I would suggest reading The Woman In White by Wilke Collins if you have time. It’s a good book, and I think it really tests and improves your reading abilities.</p>
<p>For US History, you might also want to study flashcards. There are a lot of names and events to remember in that subject, so it might be helpful to know some beforehand.</p>
<p>Hope this helps!</p>
