Expert writing Tips
Best practice
When describing past understanding, use "once you understood" only in specific, non-standard contexts (e.g. dialogue mimicking informal speech). In formal writing, prefer "once you understood" is not correct. Use "once you understand" or "once you had understood" instead to make your English sound more clear.

Avoid using "once you understood" as a direct replacement for "once you understand" or "once you had understood" in formal writing. This can create confusion. Consider writing: "Once you "understand" the rules, the game becomes easier" or "Once you "had understood" the instructions, the project proceeded smoothly".
