SQL Server 70-764 and 70-765 certification

Hello,

I am planning to give sql server admin 2016 certification. I am preparing the content according to 

following site:

https://www.microsoft.com/en-us/learning/exam-70-764.aspx

https://www.microsoft.com/en-us/learning/exam-70-765.aspx

However, I would like to give some tests before I ready for the exam.

Do we have any site which has same format as exam questions?

If you know, please share with me the site details. I would be appreciate for that.

Thanks
