How to get 57% correct

​Remember

• The first 10-12 questions are no calculator

• Read the answers before the question​

• Mark the question, guess and move on if you are not sure

• If you don't know what to do, start by graphing the question and answers!​

• ​​Remember Occam's Razor...don't overthink

• If you guess, always guess the same (1st, 2nd, 3rd, 4th choice....)

Multiple Choice

Which statement is true about the graphs of exponential functions?

• The graphs of the exponential functions eventually exceeds the graphs of the linear or quadratic functions

• The graphs of the exponential functions never exceeds the graphs of the linear or quadratic functions

No calculator section

​Remember

• The first 10-12 questions are no calculator

• These questions should not take much time

• They should not require complicated math or too many steps​
