Big Bang and the evolution of the universe test

FIRST AND MOST IMPORTANTLY! To receive credit for this Quizziziizziiziziziizz, make sure your nickname is in this format: [Class period #][Last name][First initial]. Bella Smith in period 3 would be "3SmithB".

• I spelled my name right, but didn't put the class period first

• I put the class period first, but then used my first name and last initial

• I want credit for this QZZ, so I double-checked that my nickname is in the correct format

• I believe that clever nicknames are more important than class credit. Grades are just for the quarter; "cool" lasts your whole life.
