Lots of practice papers
The idea behind the 11+ exam is that it tests innate ability; however it has been rather conclusively demonstrated that practice does improve
There are several books on sale containing endless practice questions (for both verbal and non-verbal reasoning). Exposure to these questions prior to the 11+ is invaluable, as it allows kids to develop strategies for combating them, rather than panicking during the exam.
Questions tend to be more predictable for the GL, but practice is important for both exam boards.
After a bit of practice, it is helpful to try a timed mock exam. This is something that our Tutors can help organize. Alternatively, you can organize this yourself, ideally in an unfamiliar location and with other children taking the exam around.
This is likely to be the first formal exam your children will be undertaking, so it’s important for them to practice exam skills beforehand. Timing is a particular struggle for the 11+, so it’s really important they get used to the speed of the questions and learn to stick to it (particularly with CEM, there are usually more questions than can be answered in the time limit).
Learning to prioritize is another essential exam skill. Your child should practice reading ahead, highlighting difficult questions and leaving them till last. Finally, they should get into the habit of leaving 5 minutes at the end to check answers.
It is also important that your child does not get used to only doing practice papers under particular conditions. The actual exam room will be different, and while it will be generally quiet, it may come with noises such as coughing or shuffling, which could be distracting if they are accustomed to total silence. Therefore, having them sit practice papers in various locations with small distractions (such as you walking past occasionally) will be helpful.
