SHL assessment Australia

I have been taking steps towards applying for cabin crew when the chance arises. Getting my visible tattoos removed, obtaining my RSA, learning about the company I want to apply for. I have just learned about the SHL assessment. I am fine with all of it except the maths! I have always been horrible at maths. it didn’t actually occur to me this would be something I would be tested on. I might of managed with a calculator but as far as I can see the one I would have to do a calculator isn’t allowed. I feel devastate I feel like my dream has just been wiped away. I am located in Australia. Any other cabin crew on here with any feed back? Is my dream gone?

thank you kindly xx
