Question

my brother too week to understand English grammar (remove too)​

Answer 1

Answer:

Is your brother really weak to understand English Grammar?

Explanation:

If that's true,in my opinion, your only option is to recommend him to try as many grammar exercises as possible for his age.

It's often hard for most people to understand Grammar coz at some times it doesn't match with the way we usually speak, to be frank.

Only by continuous usage of proper sentences with correct grammar usage and repeated practice of more grammar sentences can make one more well versed in English Grammar...
