Edexcel GCSE Biology Paper 1 (Higher) - 13th May 2025 [Exam Chat]

did anyone find it like a bit hard though? 🙁

I think i got like 64 minimum but most likely high-mid 70s and maybe low 80s.For the dna question i talked about double helix structure talked about made from monomers called nucletiodes each nuckletiode has a sugar phosphate and base sugar and phosphate form backbone and base is connected to sugar with complimentary hydrogen bonds with weak pairings between the two.The for the fruit i like sasid it wass crushed then detergent and salt are added ethanol glass rod (i explained in more detail but i cba to write)

wait which one was the 27 one was it the volume one bc I thought u had to do 1x1x1 not 3x3x3

for the dna structure thing i just said two strands coiled up to form a double helix and that the dna is a polymer which is a molecule made up of many sub repeating units and then gave nucleoide as an example and said it consists of a sugar phosphate backbone and deoxyribose sugar with one of the 4 base pairs linked to the sugar

It was three marks I’m 98% sure

did anyone find it like a bit hard though? 🙁
