<p>Like it has been said, it depends entirely on which school you attend after high school and what their credit-granting policies are. At the school I plan to attend, you have to score at least a 3 to receive any credit. A 3 will get you credit no matter which exam. In other words, for some exams, a 3 is as good as a 4 or 5 to earn the same amount of credit. For others, a 4 or 5 will get you more credit than a 3. For example, elective credit may be given for a 3 whereas course credit is granted for higher than a 3. And then in some cases, course credit is only granted for 5s. Whatever the school, the general rule is that most schools accept 4s and 5s, and some will take 3s.</p>
