Which is harder? Unit 4 or 5?
Unit 4 seems to be okay so far.

IMO Unit-5 is far harder, Unit-4 seems to be just an extension on Unit-2...an beginning to 'understand' rather than just remember.
The reactions in topic 4.2 are simple and take up quite a large area of the unit, many people should already know most of them anyway. There are also a lot of simple 'defining' e.g. Define pH, Pka, Pkw...which seem to be easy marks, however remembering all the organic reactions - products, catalysts, reaction type/mechanism and conditions took some time.
For Unit-5 there seems to be a lot more to remember on the inorganic and less organic - just memorising a few reactions and drawing there mechanisms.

unit 5 much harder
yeh unit 4 is extension of unit 2 with extra maths like kc and kp and acid and bases

5 is harder i think
