By mistake i have deleted the TGB(by Login to Administrator->Click on Designer Studio -> System -> Refactor -> Classes and then deleted all the TGB classes) , Now I am not able to login to the SA@TGB, Is there any way to login.

In that case, you will have to follow up with the Pega cloud team to get the deleted class back. If you are doing this for a course, you should have to re-download the system and re-do the exercises, or check with the pega academy team.
