honestly, it was good. some of the MCQs were a bit rubbish (what was that A = B +/- C +/- D question???) but overall ok. section B was as good as past papers. but a lot of people think the same thing so GB might be really high
is everyone conformed that it will be a high grade boundary?? omg I found it quite hard the organics part.. can someone plz discuss stuff for that mcq a= etc I think I marked C is it correct??

that was hard and time consuming 😡 I think I put D....... most of my classmates put C or D
what was ur lattice enthalpy value? was it like a positive number and something like 2,000 something?? and why did phosphorus have a less/or more ionization energy than sukphur?? and what about aluminium one too??

Hey!My lattice energy was smth around - 2000.. because there is a slight repulsion between the 2 electrons in the 3px orbital..And about aluminum, I wrote that the outer electron (in 3p sub shell) is shielded by inner 3s electrons -> first i.e. is lower in aluminum.
