text: Completion of SACE Stage 1 (year 11) is a prerequisite for enrolling in Stage 2 (year 12).\n\nOnce you complete Stage 1 you go onto completing Stage 2, effectively year 11 and 12.\n\nIf you have the certificate and it says that you have successfully completed Stage 2, then it means that you have completed Stage 1 too. Without stage 1 you cannot go onto stage 2.\n\nYou should contact SSABSA and get them to fix their mistake and post you a correct copy of your certificate as it is an important document you will need for TAFE or uni.\n\nHope this helps!\n\nA
