Don't do a subject just because you are good at it, make sure you enjoy it as well. Life doesn't stop during A Levels... don't forget to continue to do what you like to do out of school, BUT don't do too much. If you work consistently throughout the year, revision becomes easier, BUT that doesn't mean you can slack off. Ultimately, you will be told that if you fail your A Levels and don't go to uni/get the apprenticeship/job you are a failure. THIS IS NOT TRUE. Life happens the way it happens for a reason, Live in the moment and accept that sometimes things won't go to plan and focus on what you have learnt and not what could have been. A Levels ARE hard and they ARE a step up from GCSE, but they ARE NOT impossible. DON'T give up. Persevere and allow your failures to become your greatest successes by learning from them.
