@11plus2022 I’ll have a stab at answering your questions as the torment of the 11 plus is still fresh in my mind! Please let me caveat anything that follows as personal experience, it’s not supposed to provoke anxiety/stealth brag or encourage/discourage anyone reading from using atom!
So, for reference I have a DD, at state school. She had a regular 11 plus tutor from Jan y5 and is probably in the top 5-8 ability in her class.
We hadn’t heard of ISEB or Atom before the Autumn term of year 6 and this was actually beneficial, although we didn’t realise it at the time. DD did about 6 weeks of Atom before sitting ISEB at end of Oct. (dictated by first school in our list as they only sit once) Our state primary kindly hosted which had pro’s and cons.
When we enrolled to atom I made DD sit a mock test in all 4 areas straight away. Her highest score was 125 and her lowest 118. Within 4 weeks she got max marks (142?) in 2 areas and could consistently score 134 in all 4. After 4 weeks I started to lose faith in the programme slightly as it seemed like a lot of questions were repeated.
As noted on other threads, the content was similar but often harder than ISEB.. particularly the grammar. The biggest benefit was confidence in the layout of questions and timing… very much timing.. if they rush they miss the harder questions and don’t score as well. The algorithm is weird and definitely suits some kids more than others.
5 of DDs 6 schools were ISEB. She got 6 offers. For all the schools it was a first filter, with creative writing, interviews, group exercises to follow (or before!) So a tutor is still very helpful. Atom worked for DD as she gets both bored and stressed easily. The timed papers desensitised her to stress whilst the collecting of badges and novelty factor held her interest to learning.
I hope this helps? Ironically, despite getting into ‘more academic’ schools. DD chose a top middle school (and so did we tbh) with lots of sport and a down to earth feel. I’d say apply to a couple of stretch and a couple of easier options and see where you land. We are blessed with lots of choices!
