Dear student,
First of all you have secured very good marks in your mathematics and physics. As you want to give the improvement exam for chemistry so let me tell you as you are from ISC board you can appear for re-examination in the next year but not this year.
I would recommend you to kindly do not give the improvement exam because it's of no use because your isc percentage would be English + best three.
YES, there is a window for the improvement of your score in ISC board but you can not do it in the same year you have to wait for the next year exam to conduct to take part in the improvement exams.
Right after declaring the result, many students are not satisfied with their marks. Before 2020, it was simple process to fill the improvement exam form and after re-checking their answer sheet, candidate used to get marks after re-checking and they could give re-exam. But this year process is different.
Do it within 7 Days of declaration of results.
As you know this year their is no, re-checking system. So if you want improve your marks, then only option is to give re-exam. For that CISCE will commence examination before 1 Sept 2021.
