How can I learn network certification course at office or home?

If it is through home then we can't get the real time problems. When comes to Office then we can face some real time issues and that issues could be very much beneficiary for the Technical Learner. 

I highly recommend this website

https://www.cbtnuggets.com/

You can start with free YouTube lessons. Otherwise each vendor has its own e-learning portal, so if you are working for a partner of one of these vendors, you can request access to online training that you can do it at office or home or sometimes offline.

You can search YouTube for free courses with any language You can buy complete full courses from lynda or cbt nuggets Or you.can search for online leaning academys

Enroll in a best training academy as online course . Cisco training academy is my best
