<p>Can someone explain the differences between the SAT subject tests and the AP tests? I understand the SATs are measured to 800 and the APs are measured to 5, but I don't know much beyond that. I have taken an AP test and I plan on taking 2-4 more this year. </p>
<p>Some schools require subject tests: Do AP tests work, or do they have to be SAT subject tests?</p>
<p>Can SAT/AP tests taken at the end of senior year be used for credits? By then it's too late to use them to polish your resume, but I guess the AP classes look good anyway.</p>
<p>Simple rule: SAT IIs are used for admisson purposes at a number of colleges, APs are used for college credit purposes after you are admitted.</p>
<p>SAT IIs are required for admission by a number of colleges. APs are required by none for admission. There are a few colleges that will take APs rather than SAT IIs if you want to submit APs rather than IIs. Otherwise if you want college to know of your AP scores as part of the admission process, you simply self-report them in application, essay or just send copies of scores you received. They will not be considered in the same light as SAT IIs by colleges that require IIs and at best you should just consider APs as something a little extra to add to your file that may, or may not, be given a little consideration. APs are used for credit in college after you are admitted, including those taken senior year. Some schools use SAT IIs to determine placement (such as in language, math, chemistry) but I am not aware of any that actually give college credit for SAT IIs.</p>
<p>SAT subject tests are only multiple choice and one hour long. AP tests are usually around 2-3 hours long and include multiple choice and free response essays.</p>
<p>In addition what’s already been said, the AP exams are only administered in May and are generally taken by students who’ve taken the corresponding course that school year leading up to the exam. The Subject Tests are taken on your own terms and registered for just like the SAT (usually on the same tests dates as the SAT as well).</p>
<p>So in most cases one type of test can not be used to replace the other.</p>
<p>They serve different purposes, have different types of questions, and are administered differently.</p>
<p>If you are well prepared for the AP test (to get college credit and to demonstrate a challenging course load for admissions purposes), you wil be well prepared for the multiple choice SAT Subject Matter tests.</p>
<p>They are just two different national tests, but APs are just more rigorous and course oriented. APs have multiple choice section and writing (which comes out of your memory box and pure practice). In some schools, they will allow APs to fulfill college credits, but in others you will have to take placement tests anyways (if you took the Aps and/or SAT II subject test for the course you will do fine).</p>
