The exam simulator is updated to the latest edition. There are no planned changes to the CAPM exam in 2021 that I know of. If you raise a ticket with the support team, they'd be able to let you know what your options are of changing to the 2021 simulator (which has been updated for the PMP exam changes) if you did change your exam date.

Hello, I understand the CAPM® Exam was updated in September 2019. Is my current exam simulator updated to reflect the new content or is there a further exam update being rolled out in 2021 - apologies, a little confused (my exam is schedule 29th Dec).

If I reschedule my exam to Jan 2021, am I still to use the current simulator?
Many thanks.
