Not all are from the bio portion. You can get good marks if you make flow charts. Figure work in topics like "learning" and "development" will enable you to score high.

The examiner wants to see if your concepts are clear. So any answer supported with aids and diagrams will fetch a high score for you. The best part about Psychology is that it doesn't demand unnecessary lengthy answers. A complete and to the point answer will do. No need to beat about the bush.
