under module 1:lesson 5 Quiz, the question: “How can you prevent your sugaring arm from getting tired?” the options are: a. Try to take regular breaks between larger treatment sessions. b. Crack your wrists and knuckles before beginning. c. Use the ErgoWave to review and master your hand positioning. d. Work toward the softest sugar you can handle.
the only incorrect option is cracking your knuckles. But the quiz has each option as “incorrect” so no matter what you choose it marks it as incorrect.
