if we gave hsc results for re-checking then by how much duration we can get it re checked ?
Re-checking of copies involves a long process including registration, payment, acceptance of the images of original answer sheets, raising objections, validation of objections, etc. So, you may expect that re-checking of your copies will take around 1 month and in the worst case, it may even take more than 1 month. For more information, you may go to the website of your respective board and check the policies.
Hope it helps.
