How can I manage my time in the IB Psychology paper one.

I suggest first looking at the questions and the command terms to determine what they are actually asking you to do. Then plan out responses to all the questions (case studies, introductions etc). Once you have planned your responses begin writing and use your plan as a checklist as you finish each question. This makes the process of essay writing in psychology much easier and if you learn plans for each case study it will come to you much quicker and pay more attention to the structure.
