If I circled an OMR sheet with a black pen instead of a pen in CA?
Instead of pencil is what u meant right.? Nothing just chill ur answer will be evaluated by computer system, the only reason ICAI recommends circles of answer in Pencil is bcoz in case of mistakes one can easily change the answer with less efforts and does effect the sheet as it needs to be scanned in system. so I hope u got my point All the best for results
