The first three units are physical chemistry (23 marks), the next two inorganic (14 marks), and the last five organic (33 marks). The practical examination carries 30 marks, of which volumetric analysis and salt analysis take 8 each.

Using this to plan
- Organic chemistry, the last five units, is 33 marks: the largest block.
- Because marks are even across units, leaving out any one chapter costs 6 to 9 marks. There is no safe chapter to skip.
- Volumetric analysis and salt analysis are 16 of the 30 practical marks. Practise both until they are routine.
