General marking principles for Advanced Higher Chemistry This information is provided to help you understand the general principles you must apply when marking candidate responses to questions in this paper. These principles must be read in conjunction with the detailed marking instructions, which identify the key features required in candidate

group, a mark should only be awarded if the “O” or “N” are bonded to a carbon, i.e. not OH-CH 2 and NH 2-CH 2. When drawing structural formulae, a mark should only be awarded if the bond points to the “correct” atom. This marking instruction must only be applied a maximum of once per question. The example below would be incorrect.

GENERAL MARKING ADVICE: Chemistry Higher The marking schemes are written to assist in determining the “minimal acceptable answer” rather than listing every possible correct and incorrect answer. The following notes are offered to support Markers in making judgements on candidates’ evidence, and apply to marking both end of unit

the marking instructions will give clear guidance on the assignment or partial marks. (f) Unless a numerical question specifically requires evidence of working to be shown, full marks should be awarded for a correct final answer (including units) on its own.
