does on MKCL website every student have different question aur just the sequence are changed and if my PC doesn't have camera so what should I do please reply very urgent

Firstly, there are no such informations available regarding the examination about the question pattern and the shuffling.

Secondly, if your PC don't have web cam then you have to arrange a webcam. You can get webcams on amazon, flipkart. Just type on the search bar 'External Webcam' and you can buy it. Without a webcam you can't give the examination as per the policies of MKCL.

In point number 9 of the official notification its stated that:

Using Web camera is mandatory to attempt online exam. Web camera should be connected to the PC/Laptop on which the exam is being attempted and it should be always in ON state.

In point number 11 of the official guideline its provided that:

If the web camera is disconnected from the PC/Laptop any time during the exam, then exam will stop immediately. The exam can be started only when web cam is connected again & then exam will start from the point where it had stopped earlier.

So be careful and you must buy or get in any means a webcam else you will not be able to give the exam.
