I've really focused only cloning. Like tissue culture, cuttings, embryo transplants, adult cell cloning and genetic modification

Honestly in b1 they usually ask anything equally, from in depth topics to basic points. Just be prepared to answer anything

If your still revising now, focus on the things you are struggling with including answering past questions and learning from the mistakes you made, that's what I've been doing over the weekend, and if you get free lessons or are with your biology teacher or whatever tomorrow just do anything (DONT CRAM!)

Break it up into what each group of living things do.
Plants photosynthesise and respire (you should know these reactions well - learn the products and reactants)
Animals respire + humans combust fossil fuels / wood
Microorganisms decompose dead plants and animals (and release CO2)
