Century Tech vs Atom Learning for the ISEB pre test

[grumpycamel]

I only recently learned that Century Tech, rather than Atom, will be designing the ISEB pre-test. DS is taking the ISEB next month and has been practising on Atom. I am panicking slightly, wondering if this will be a disadvantage for him and if I should now fork out for the Century home learning platform subscription. I don't know if there are any significant differences between the two and whether his progress on Atom will be a reliable indicator of how he does on the exam. Does anyone have any advice? Thank you.

Dd has tried the century tech platform on a trial basis. It’s rather different to Atom where answers are not always given after an incorrect answer. I found it rather a frustrating way of learning!
we have decided to stick to atom for now and hope for the best ……

Thanks Roses81. We tried it too. It is a very clunky platform and DS doesn't like it at all. We are also sticking to atom and hoping for the best!
