where can i verify solution for jee advanced mock test 1 conducted by cbse

Dear Naveen,

First, JEE Advanced is not conducted by CBSE. It's conducted by different IITs every year. For 2018, JEE Advanced is being held by IIT Kanpur. So, the mock test is also released by IIT Kanpur. Secondly, the solution or result is not provided by any mock test, as the facility is just to make you familiar with the online exam taking system and help you increase your speed, problem solving ability and polish your time management skill. So, you can just focus on these aspects which is the purpose of the mock test.

Solutions are not provided for jee advance mock test as they are just to give you anatomical feeling of exam.
