@William
Here are my answers for you:
"Am I going to be able to have similar access for the 2021 Exam contents ?"
>> We are providing a free simulator upgrade to those who have an active account on 2020-12-31. Please see here for details:
www.project-management-prepcast.com/pmp-exam-update
>> The formulas don't change so no upgrade is necessary.
"I understood that the 2021 exam contents needs to be teached live, what will be the cost for this live training ? Any credit for someone like me who rencently join PM Prepcast?"
>> Unfortunately, we cannot offer this because of the added expense of the live teacher.
