• With revision tries to take the examination again
• Tries for a change to do with leaving a second time
• Take another meeting
• Pose model again (tires badly)
• What remains is about one exam 18-down
• Son in row sent back for further examination

• Relax -- welcoming one test that must be repeated
• Second test in balance, I observed
