Basically, you only need to know about the principles of these spectroscopic techniques, and how to apply the techniques to specific situations. Also, interpreting data questions will also be asked (eg. NMR Spectrums and determining what compound it is)
With Aspirin, questions are asked about the production of Aspirin from salicylic acid, and with Relenza, you only need to have a general idea of how defective proteins can indicate the presence of a disease (eg. You dont need to know that Relenza binds onto the neuraminidase of the flu virus germ, thereby preventing it from spreading infection to the rest of the body, you only need a general knowledge of protein markers)
Green Chemistry principles are general knowledge, and for 3,4, you dont really need to know about atom economy and memorise the principles; its just general knowledge really.
As for Galvanic Cells, thats Unit 4, and for the new syllabus, you only need to know the general features of a galvanic cell, not the different applications and the electrolytes involved (eg. you dont need to memorise the button cell)
So Basically, emphasise greatly on Spectroscopic Techniques, and to a lesser extent, aspirin
Hope that helped
