<p>Students your age in the UK are preparing for their A-levels, which are difficult tests that will affect their entrance into university. These are all in specific subjects, and the typical UK student will take three of these, some take more than three.</p>
<p>So to determine admissions for American students, UK universities look at the closest thing that the USA has to A-levels, which are AP tests and advances SATs.</p>
<p>A student planning to “read” (what Yanks call “major in”) English will probably do A-levels in English, History, and probably a foreign language (usually French). But I am sure other combinations would be possible, as long as they included English.</p>
<p>So, yes, you are being asked to take three tests, one in English, two in other subjects. These would need to be either AP exams or SAT subject tests. If you won’t be taking and passing these tests, you won’t get into a British college or university, at least as an undergraduate. Think about going for graduate school, or going as part of a “study abroad” program in an American school.</p>
<p>Remember that Oxford and Cambridge are the two best, hardest to get into British universities. There are many many other colleges and universities in Britain that are easier to get into.</p>
<p>I don’t know a great deal about how the “projecting” your results on AP exams works. Your offer will probably be conditional on the scores you get on your AP tests (so a uni will say, “We will accept you if you really do score X, Y, and Z on your AP tests as you have projected.”)</p>
