Memorising standard squares, cubes and roots

Question

Hi GMAT experts,

I'm in the beginning phase of my GMAT preparation, and I was wondering if there's anything apart from the below that I should memorise or know by heart. So far I have the following:

1, Squares and cubes of numbers till 20
2, Square roots and cube roots of numbers till 20
3, Base fractions and their percentage approximations.

Anything else you suggest will be really helpful in my preparation! Thank you so much!

Regards,
Kelsier.

The divisibility rules listed in this post can be helpful, though I personally never bothered to use the one for 11.

I also found it helpful to practice prime factorization by doing prime factorization of all the numbers from 1 to 200 a couple times in my head.
