Repitition of Math topics and Reading Gita repeatedly

Some children wonder they started learning fractions in Grade 2 & did again in say grade 4 & then they keep having to do again in later grades as well.

Well as they get older of course the level of detail & the complexity of the problems they solve progresses with the ability of the child .

And people who read Gita repeatedly vouch that they learn more / deeper meanings each time. They say depending on their level of consciousness and satwa, the understanding increases as a continuous process.

For fundamentals truths ( Maths as well as Gita) repeated practice and gradual increase in complexity and understanding is important.
