In the Sixth Form (that is, Lower Six and Upper Six, or Year 12 and Year 13), students learn a minimum of three subjects according to the Advanced Level curriculum of CIE and ZIMSEC. In Lower Six, students can choose to write tests for the Cambridge International AS Level certificate (half the content of Advanced Level is tested, the certificate is given by CIE) then write tests again in Upper Six for the full Cambridge International A Level certificate. Another option is to write the Cambridge International A Level and or the ZIMSEC GCE Advanced Level tests in Upper Six.
