the test is fairly hard because it could also consist of year 11 topic which u may or may not have touched on (unless you are an accelerated student, then I think it's not that hard to make it into A1). It does become harder to get into A1 as more students enrol since there are a limited number of spots, but they aren't super strict with numbers so if you are great and amazing then you will get a spot otherwise just slowly build ur way up by achieving well in your quizzes throughout the term
