For my youngest DC, we used Atom Learning for the 11+ prep and it was perfect for us/DC as it was adaptive, clear to follow, stretching but also easily manageable for the child and provided a clear path. For us, it was also highly correlated with DC's 11+ results.
For my eldest DC, GCSEs are now around the corner and I'd love to find something similar to cover the 3 sciences and maths. Is there something like this - adaptive and online?
Looking for recommendations, please.
