About this academy. Exercises use fictional or permission-cleared data and are simulated training, not supervised project experience. Completing modules does not confer professional registration, LTA approval or recognised Singapore working experience, and does not guarantee employment. Calculators produce preliminary outputs for learning and checking; they are not PE-endorsed designs. Official requirements are in the documents published by LTA and other issuing bodies — always use the edition your contract specifies.
