Hi, I ended up with A*A*A (maths, electronics, physics respectively) and this was unexpected so I didn't anticipate to be able to give people advise
For me, the best example is with Electronics, where I got 30/110 in the mock but now have A*. This is because I really, really really tried to come to complete terms with the course 2 months before the exams, questioning whether I understood things that were in the textbook and making sure that I understood how everything fits together and leads on from one another. Following this, I did all of the past papers which refined and clarified the parts of the course that I need to know, and the types of questions I should practise and redo multiple times.
For Maths, the last part of that is more significant; I got an E in the first C3 paper but 96/100 on he day of the exam. It's a case of doing as many questions as possible during and after the teaching of the methods, in order:
- to increase the chances of not messing up in the exam (the whole system is deeply flawed, so much of it is based on how the exams happen to go on the day of the exam)
- to encounter questions that don't spoon-feed you the way in which to go about solving them
I didn't get an A* in Physics but I think that an A is absolutely good enough - although your question is asking about tips for an A* so I can't say anything about that for this subject! Although I'm sure the above is still applicable to it
I wouldn't use the word 'harder' when comparing A2 with AS, but I'd say that they are generally more complex, resulting in more work needing to be done to adapt to them. Whether this is in fact the precise definition of 'harder' is a possibility, but I believe that my description is far more useful.
Nice results
