Why is work experience soo hard 😫

I am currently studying in sixth form as a year 12 student studying both OCR CTEC Applied Science and A Level Biology and there hasn't been anything as hard as getting work experience especially in a scientific-based work experience and I have tried to email companies multiple times and most of the time they are unreachable or just don't have a spot for me. I have also thought about virtual work experience but have been told multiple times that it isn't worth the money. If you have any recommendations please inform me as soon as possible thank you

Where are you based? I work in a small vet lab that often has vistors. It's a bit dry but If you need it for your course and you are near, we may be able to accomodate you.
