Anyone have 2015 igcse papers for b3?

Can someone please help me. Is speciation along the lines of were 2 species are isolated by either geographical barriers or something and they evolve so successful genes are passed on to offspring and forms a different species?

p.s Good Luck everyone :smile:

I'm much more confident for B2 than I am for B3, just so many comparison questions in B3 for different systems (circulatory, kidney, heart) I'm bound to mix something up. Really hoping for some long questions on the heart etc., been revising that really hard. Swear I've done every practice paper now :smile:

Past papers are a problem with B3, as there are only 3, I've done them all too, and I'm wishing there were more :/

Good luck everyone
