Advanced Placement FAQs

Am I eligible to enroll in AP courses?

To see the programs and courses for which you are eligible, check the CTY Eligibility Assessment if you have test scores for SCAT, STB, SAT, PSAT 8/9 or ACT tests, or check the tables showing eligibility guidelines on the Admissions and Eligibility page. You should also review the course descriptions by clicking on the course title in the Course Catalog, since many courses have prerequisites.

Can I enroll in AP courses even though I am not in high school yet?

All AP courses are only open to students in grades 9-12 who meet the prerequisites. Generally, AP courses are not recommended for students below grade 9 who intend to take the exam, since AP exam scores are removed from the College Board active computer files and archived four years after the test date.

How many AP courses can a student take?

CTY Online Programs AP courses are demanding and require a significant time commitment. (For example, AP Physics requires 20 hours per week during spring and summer.) Students should not attempt more than one AP course at a time. Students considering enrolling in multiple AP courses at one time should first confer with program administration by email before registering.

Why do students enroll in AP courses and take AP exams?

Students who undertake AP level course work in high school demonstrate their readiness for college-level work and their willingness to tackle challenging academic material. Many universities and colleges award advanced standing or credit for college-level courses based on the scores a student achieves on AP tests taken in high school. Depending on the university's policies, the student may be able to begin studying the subject at a higher level or be awarded credit that will count toward a degree with that university. Policies about awards, advanced standing, and required AP scores vary by university. Some AP courses also prepare students to take SAT Subject Tests.

Are CTY Online Programs AP courses approved by the College Board?

All CTY Online Programs courses with “AP” in the title have been reviewed and approved by the College Board to use the "AP" designation. To view the College Board’s AP Course Ledger that lists all AP courses offered worldwide that were reviewed by the Advanced Placement Program Audit and are authorized to include the “AP” designation, visit the AP Course Ledger website and type in "Center for Talented Youth at Johns Hopkins University" as the high school name.

Do CTY Online Programs AP science courses include labs?

CTY Online Programs AP science courses include 20-25 (depending on the course) "hybrid labs."  Our Hybrid labs include both hands-on experiments that students can safely perform at home with easy to obtain materials, and virtual experiments for components of the labs that would not be feasible for students to do at home. Our virtual experiments are real experiments (not simulations), and each student's results differ according to the accuracy and precision of his or her data-gathering techniques. Students who enroll in our AP Chemistry course must purchase a chemistry kit containing chemicals and instruments necessary for the hands-on experiments. (Please note that this is not included in the course tuition.) This combined hands-on and virtual approach allows students to develop practical skills in manipulating instruments and materials, and to perform multiple trials of lab procedures that would be dangerous, costly, and time-consuming in the physical lab. In CTY Online Programs AP science courses, students perform all of the labs on which they will be tested on the AP exams.

When are CTY's AP courses offered?

All CTY Online Programs AP courses are offered in a session-based format, with specific start and end dates. All courses are offered for a 30-week academic year session; most are also offered during intensive 12-week spring and summer sessions. Students receive a course schedule specifying due dates for assignments and tests. See the AP Calendar for specific start and end dates.

AP Calculus AB, AP Calculus BC, Calculus C, and AP Statistics follow the program guidelines for CTY Online Programs individually paced math courses. Students may enroll in AP Calculus and AP Statistics at any time during the year.  Students intending to take one of the AP exams should enroll by early January at the latest to allow enough time to complete the course before the AP tests in May.

Can students take an AP course for review and not for a grade?

CTY allows a student to audit an online course. To audit an online course means:

  • The course is not taken for a grade.
  • If the course is an AP or individually paced course, the student is allowed to move throughout the course, skipping around as needed.
  • A student on audit status still has access to all course materials and their CTY Online Programs instructor, who will meet with the student as needed, monitor progress, email weekly as usual, and send grades or feedback as appropriate.
  • A student on audit status taking any graded assessments must follow all exam, course and CTY policies (in particular, the honor code).
  • No course completion documents (for individually paced courses) or final evaluations (for session-based courses) will be sent once the enrollment ends.
  • An audited course will not appear on the student’s official academic record.

A student can go on audit status at any time during their enrollment, but cannot go back and cannot re-take an audited class for a grade. A student cannot audit a course if the student is on a provisional admission.  Auditing a course does not satisfy any prerequisite conditions for future courses that require successful completion of the course taken for audit. There is no change in tuition for a student on audit status.

To go on audit status, a parent/guardian must send an email request to the instructor.

Can I take a vacation during my CTY Online Programs AP course?

In general, students who are unable to participate in a session-based AP course for an extended period of time are discouraged from applying for that session. Students who will be away for a vacation (one week or less) should let the instructor know as early in the session as possible. The instructor will try to work with them to arrange a schedule for make-up assignments.

Students in the individually paced AP Calculus and AP Statistics courses are the exception to this general rule. AP Calculus and AP Statistics students can pause their time through MyCTY if they will be away for 7 days or longer. Pause requests cannot be made retroactively, or by phone, email, or through the student’s instructor.

Will I be able to access course materials to study for the AP exam?

Students will be able to access their session-based AP courses for review until the next AP test dates. Students enrolled in individually paced AP courses (AP Calculus and AP Statistics) will have access to the course content while the course is active. Once an individually paced AP course is complete, students will no longer have access to the online course materials.
