Hey,
I just wrote out a big long post about this in another person thread practically 5 minutes before you posted your thread, i hope it might be useful to you aswell
Getting 5 A's is definetly achievable, i fell short but i never really aimed for 5 A's.
Basically first off you want to go onto Ebay/Play.com and buy second hand past papers, practice papers, revision guides, how to pass guides etc. Buy as many as you think you will need, believe me that you will run out of past papers to practice on. Guides are a great resource for telling you what you need to know, some have nice little summaries which are good time savers too. Thats the first step, the only step which requires you to buy some resources.
Tip for you btw, dont buy the most recent editions of past paper books - hence why you want to buy second hand ones - as you can get all of the last 4-5 years of papers from the sqa site ... its the pre 2007 papers you want to try and find.
Once you've got your books then download all of the available past papers, answers, arrangements documents, external reports and practice papers from the SQA site for each of your subjects. Take a quick look through all of these to get an idea of what to expect from the course.
Over the summer perhaps have a look at some of the revision booksa you will have, don't overdo it. Just get a basic idea what's covered i nthe courses and how much you will already need to know. Find out what bits from SG are needed and make sure you understand them all fully.
Thats the preparation phase done
Once your in your classes then take notes if you can, try to make them detailed and add in diagrams or any of your teachers comments throughout the lessons. Notes are important but it is far more valuable to listen to him and take in what he is saying, if you sit and take notes and understad nothing he is teaching then your doing yourself no favours. If you cant take notes and keep up with his teaching then simply make rough notes and you can add to them later on that day.
Make sure you keep up with all of the weekly homeworks, aim for 90%+ all of the time! - generally the easiest part of the course is unit 1. If there is anything, and i really do mean anything, that you dont quite get then ask your teacher about it. Most of the stuff from unit 1 you'll find will crop up again in later units and it will become more advanced, building on what you should already know.
Don't let people fool you by telling you to study every night. That is not necessary. You will want to study say 1 or 2 nights per week ontop of your homework. By study i simply mean go over the stuff youve learned this week, make sure that you really do know it all and try some examples. Thats it.
Follow this pattern for the rest of the year and you are guaranteed to achieve 5 A's.
When it comes exam time you will want to begin studying perhaps around 1 months before the exams start. Start slowly, 1 or 2 nights per week. Gradually build it up depending on how well you are handling the courses and how you feel. Eventually you might end up on 3-4 nights per week. It all depends on yourself, how much work you do throughout the year and how much you feel that you need to do. By this point you should have done every past papers available to you (or atleast most of them) Make sure that you understand every question that you get wrong, ask a teacher if you need to. Then Analyses the papers, you will notice trends - certain question come up every single year and you can bank on getting those marks - you will realise that there are only so many question that you can be asked and thus you can easily prepare to get your A by familiarising yourself with the questions.
It basically boils down to how much you work during the year, and then the few weeks before your exam. If your motivated enough then you will easily get your 5 A's
