Supplementary exam ISC

So I am planning on giving isc supplementary exam 2026. As we know to appear for supplementary exam we need to appear for both practical and theory and submit practical notebooks and projects again. But one problem for me, I have appeared for isc exam in 2024 and the practical notebooks that I did for isc 2024 I don't have those notebooks now. The school returned them to us and useless me I have lost the practical notebooks of all the subjects that's physics chemistry and biology. I feel like crying 😭. I don't know. Does anyone of you have suggestions what I can do in this situation or can anyone who have give isc supplementary exam before guide me on what can be done pls 😭🙏. Please don't ignore this 🙏.
