Did your teachers give you the Practical Skills handbook?

http://www.ocr.org.uk/Images/70646-p...s-handbook.pdf

Pages 28-33 are seriously useful/important for the evaluative paper.

Yes do u have any tips
Wait did you have it yesterday? If not

Basically there is nothing on mass spec

You need to know limitations of infrared spec
You need to know how to calculate percentage error for burette volumetric flask and pipettes
You need to know how the mean titre will change if you make mistakes in your titration
You need to be able to draw e/z isomers
Remember the reactions of alcohols
Remember the test for unsaturation
And you need to be able to write equations for compound with more than one functional group reacting with metals
