My DD was in the "above expectations" category, following through to A levels she achieved A, B, B (AAA forecast) so not as bright as some.
From a young age, we spent time taking her out, naming new things as we saw them, also enjoying books together, doing puzzles as well as workbooks (she couldn't get enough of the latter before starting school). She was determined to get a scholarship for sixth form, we weren't convinced, and told her if she wanted it, she had to do all the ground work - all we would do was take her to look at schools andfill in financial paperwork - she did her research, made enquiries, spoke to staff.
Moving through school, DD became very independent - I knew other parents were helping with homework - she wouldn't let us even look most of the time. All we did was provide her with the materials she needed.

So with us I think is was a combination of support on our part, and determination on hers.
