About the new exam cka

Hello an important question, please next week I have scheduled my CKA exam, but now I see that the exam has dropped in time:

- BEFORE: 3 Hours.
- NOW: 2 Hours.

My question is this is because the 24 questions have been reduced in ( Amount of questions ) or is it that now the questions are less difficult.

Please, if you could detail me, would help me a lot.

Thank you.
