Hi aspirant,

CBSE had conducted the improvement examination for the candidates who are not satisfied with the marks allotted to them based upon internal assessment. As the name states improvement ,the improved marks are reflected in your marksheet and i f you score less in improvement then your previous marks are considered and not your current marks as the current marks will not help you in improving your score. So in the original marksheet,your highest marks will be reflected or shown

Hope it helps!!
