Take lessons seriously and work hard:
Putting in hard work and taking lessons seriously is vital; teachers have to see the ability you have in order to set the grades for you that they feel are realistic enough for you. This is why it is important that you work harder than ever as you do not want to be dropping into lower classes come GCSE and A-Level exam times, as you will want to be at the very least in top classes; were lessons are taught at a much higher level; which enable you to achieve those grades. Also, teachers have the power to assess your work, you put in your class and out of class as part of assignments towards your final grades, so it is more than vital that you put in the extra hard work needed.
Take mock exams seriously:
Teachers will be setting out a lot of mock exams and assignments to get you ready for the real exams, so it is imperative that you take the mock exams just as important as the real exams. The reason for this is that it will give you a sense of idea of where you are at as grade as well as your teachers, which is really important as they will be able to determine the areas that you need more help in and start preparing you in that area that needs more help for the real exam. Also, some mock exams can be taken into consideration towards your final grade, which is why its important you give it your very best.
Talk to your teachers:
Talking to your teachers is more than important as you need to be on the same page as them, meaning they choose whatever form of assessment they think is best; however, this can only be done based on your grades. So it is important that you have a chat with your teachers on how they plan to grade you, this will be an advantage point for you as you will be receiving feedback on areas that they will be looking out to grade you more on, which will give you the advantage point of being prepared more in that area.
