@DeepakReddyC if the domain name of the email you use to log into Pega websites does not reflect the name of the affiliated company name (eg _[areteanstech.com](http://areteanstech.com)_) but if you are using gmail or hotmail or something similar then your community account will only be considered as ‘_guest_’ and as reflected in the screenshots I provided, these courses are only for Partners and Clients therefore they will not be visible to you. Please see the Pega Accounts [FAQ](https://academy.pega.com/pega-account-and-profile-faqs)page which explains how you need to change your Primary email to be the correct one for the affiliated company. Our [Community Accounts FAQ](https://community.pega.com/account-faqs?) page also has details on how to change and confirm your company email.
