Passing the skills test is not easy if you were not good at maths in school. Answering a maths question in 18 seconds can be challenging but if you can't do it yet, it doesn't mean that you would not make an outstanding teacher.
Allow me to help you by teaching you a series of shortcuts which will get you through this test. I have developer these great techniques while helping other like you to pass their QTS numeracy skills test.
This online course is designed according to the skills test curriculum and it covers everything you need to know to pass this test. The course also contains specific methods appropriate for this type of test, designed by a subject specialist.
I estimate that you can pass your skills test in a week, if you start the course now and you practice about 2 hours each day.
