@ KHADARBASHA 
online exams are only for jee main as of now , jee advanced are completely offline as of the latest rule and regulation . 
and we have previous year papers on our websites , and as its a online level paper , so, its very very difficult to provide the online paper , 
u have to write online paper in the center only , in the center u will be provided with a computer , and a mouse . 
u have to write the answer on the mouse . 
the things are all easy , u can even check out the online mock test on our website . 
ALL THE BEST ..
