Hello,

As per the instructions available in the official website it is necessary to appear for first mock test and second mock to appear for the actual test. The mock test helps the candidate to get used to the Online Remote Proctored Exam mode and to check if the devices are compatible and has the required specifications. If you have logged in for while during the first mock test you will not face any problem. But if you haven't logged in then you might not be able to appear for the actual test.
