yes , for sure , but dnt think of dropping now , dropping is the thing that u have to think after the result have declared .
beacuse the story of dropping is not always yield good result . there are some people who did drop for 1 year and also getting the worse rank than that of the current year .
so, get prepared this year and attempt jee with full strategy , so, that u can crack that in one attempt only .
otherwise , if good colleges u wl not get , in that case u should think upon dropping , not now .
and abt the condition , yes , u can but 75 percent in board are required to attempt mains . 2018 .
ALL THE BEST ..
