 When you’re prepared and ready to schedule your exam, you can register from any certification details page on the [{% data variables.product.prodname_certifications_singular %} Registration](https://learn.github.com/credentials) page.
 
-During the scheduling process you can choose if you want to take the exam in a local test center or online. With an online proctored exam, you can take your exam at almost any time using your own computer, but it requires installation of a secure browser and reliable access to the internet. Local test centers provide a secure computer environment to take your exam. For more information, see [Computer specifications](https://www.psiexams.com/become-psi-test-center/computer-specifications/) in the PSI documentation.
+During the scheduling process you can choose if you want to take the exam in a local test center or online. With an online proctored exam, you have the freedom to take the exam almost anywhere, but you’ll be responsible for making sure your computer and exam area meet security standards. Local test centers are a great choice if you prefer a quiet, pre-configured environment without the worry of testing your computer and downloading software to meet Microsoft’s security standards. If you decide to take your exam online, you’ll run a system pre-check to see if the computer you’ll be using meets the requirements before registering. For detailed instructions on how to perform the system pre-check, see [About online exams with Pearson VUE](https://learn.microsoft.com/en-us/credentials/certifications/online-exams) or check the [FAQ](https://learn.microsoft.com/en-us/credentials/certifications/frequently-asked-questions?source=recommendations). If you have any technical or scheduling concerns, you can contact [support](https://learn.microsoft.com/en-us/credentials/support/help).
 
-The {% data variables.product.prodname_certifications_singular %} program partners with PSI to deliver both online and in-person certification exams. After your register, the first appointment offered to you will be a minimum of 24 hours from the time of booking. When you sign up for an exam, PSI will send you a confirmation window, and you have a 2-month window to schedule. If you fail to schedule within that time frame, PSI will send you a final email reminder. If you miss your scheduling window, you will need to repeat the scheduling steps.
