Can my student use an on-screen calculator if I use LockDown Browser in Canvas New Quizzes?

Yes. 

If you are using New Quizzes in the Test Centers and are allowing students to use a calculator, this feature must be active for students who may not have or forgot to bring their own simple or scientific calculator.

• Select the quiz you want to edit

Select Build

• Select Settings

• Find Allow Calculator

• Toggle this setting to ON:

• Choose Basic or Scientific calculator types. You can only choose one
  • Remember: your students can bring in their own allowed kinds of personal calculators
• Select Return in the upper right-hand corner of your screen to save the setting
• Do NOT make any changes in the LockDown Browser dashboard calculator settings
• Be sure to select which kind of calculator(s) you want to allow when you submit your exam registration via Registerblast.
