Congratulations! You have just started to explore the networking worlds by taking the very first semester of CCNAv7 Routing and Switching course, provided by Cisco. All materials are official materials. Education should not be costly, so start your IT career by taking this course materials with a low cost, learn and try to prove your expertise.

If you have any questions about course contents like slides, pdf's, packet tracer files, please ask questions. Any kind of discussion is highly preferable. The motive of this course is to give you the materials that are provided by cisco so that you can learn about networking, it's protocols, addressing, end device and intermediary device configuration, network security, design and troubleshooting and much more.

Also if you have any kind of recommendation or need of further assistance about extra materials, you can also ask about it.

Semester-1 is the first and fundamental course of the 3 semesters CCNAv7 course where the other semesters are:

a) Semester-2:SRWE (Switching, Routing and Wireless Essentials)

b) Semester-3:ENSA (Enterprise Networking,Security and Automation)

I will also provide materials for those two semesters as well. Since there are lot of materials to be uploaded, so I think it's a better idea to upload them as a separate course.

Good luck and Happy Networking !!!
