Hello, I noticed that some of the answers for Cisco Essential Version 4.1 are unavailable.

I can see these:
Chapter 1
Chapter 10
Chapter Final Exam 1-10
Chapter 11
Chapter 14
Chapter 15
Chapter Final Exam 11-16
Windows 7

But the rest I cannot see. If you could fix this, if possible, it would really help. Thank you.
