The best approach is to do the test then review in detail the questions and their solutions – this is key and will help to understand the different question types and if another similar question is presented in the real test then it won’t be a surprise. I then suggest you repeat the test possibly after a day or a few hours. You should aim to get 80-90% to have a good chance. These practice test questions and answers are randomly ordered and will help familiarise you with the questions but ultimately it is your performance in the real test and any practice tests are simply an indicator. A lot of parents have had a good result using the process above.

All the best to achieving your future success!
