If you are planning on taking the exam on a personal laptop, that's completely fine! Keep in mind that you are free to hook up one or many external monitors to the laptop while taking the exam. In some cases, using an external monitor will fit more details found on the Horizon dashboard and more output from the terminal. If you have an external monitor available (28" or larger), you may want to use it instead of relying on a small laptop screen.
