The most important thing before you start is to ask yourself the above question, think seriously about your response, and then set yourself goals accordingly. What you need to know now is that entry into all of the professional courses is extremely competitive, and people don't gain entry to any of them by accident.

How important is it to you that you gain entry to your chosen professional course? What would you do if you didn't make it? Thinking about the answers to these kinds of questions now can give you the motivation to achieve what you need to from this year.

If you're just "having a go" then be clear about it from the outset, and don't berate yourself for scoring less than your friends who feel they "absolutely must" get into their chosen professional course. If you're "going all in" to get into one of the professional courses then you will make things a lot easier on yourself if you decide this early on and start working hard from the outset.
