Here is how my trial usually goes:

My trials are a maximum of 45mins, and there are three phases:

  1. Preliminary Questions
    In this section, the Testificate is asked questions on base conversions, bit-wise operations, and any circuit in the link below. (from Logic Circuits down). Usually five questions
    Redstone circuits – Minecraft Wiki
  2. Build Phase
    Testificates build their circuit as specified in the application.
  3. Trial Questions
    I ask some questions to evaluate the Testificate’s understanding of their circuit. They may be asked to describe what certain parts do.
