All SQA past papers can be found by using the following link – SQA past papers
You should practice past papers on a weekly basis.
Now that the National 5 course has been up and running since 2014 the past papers are building up nicely on the SQA website (The last 5 years at least, but don’t worry papers older than that can be found here). These will continue to build up as the years pass. Please note that the course was updated by the SQA in 2017, past papers after this time will therefore be the most similar to that of your final exam. If you require additional practice, see the suggested textbooks section. Hodder and Gibson have published specimen papers and Leckie and Leckie have published practice papers.
TIPS AND HINTS
- To begin with, concentrate on the questions you can do from the chapters we have covered.
- In addition, look out any questions that are problem solving, these will not pertain to any one chapter.
- As a rule of thumb, if it is a 1-mark questions you will be required to provide 1 correct point, if it is a 2-mark question you will be required to provide 2 correct points and so on.
- Use the marking scheme to mark your paper. Take a note of questions which were wrong and revisit them at a later date to see if you have learned from your mistakes.
- As you become more confident complete papers under timed conditions. Another rough rule of thumb is one minute for one mark, this will leave you enough time to check over your paper at the end.
- If you are stuck at a question do not dwell on it, move on…. do the questions you feel confident with first and return to those you are unsure of at the end.
- The golden rule of exams is to, READ ALL QUESTIONS CAREFULLY…. especially essay questions, decode the question, ask yourself “what is it asking me?”.
- Your spelling does not have to be perfect, however make sure your paper is legible, if a marker cannot clearly read it, they will mark it wrong.
- Lastly, DO NOT leave blank spaces, attempt ALL questions, if you have to take an intelligent guess! You might scrape a mark; this could be the difference between an A or a B.
Following the above advice will ensure you are equipped with the skills you require to pass your final exam. It takes practice to understand the types of questions you are asked, and to answer them in the language that is expected of you. This is why analysing the marking instructions is so important.
