I've a doubt. In jenson alpha I made a stupid blunder by taking exp rate - actual rate but ranked correctly .. Will they give at least 4 out of 8 for calculating ke correctly ?? I feel horrible now :( and also in leasing by mistake I added tax saved on dep and interest instead of deducting. . will they give at least 4 marks for other workings ?? My lease outflow is right and depreciation and interest schedule is also right.
