Do you need to remember pH ranges of indicators?

Eg. Memorising that Methyl Orange has pH range 3-4.5 and is red for anything less than 3 and yellow for anything more than 4.5

Is it necessary? How often will they ask something that specifically requires this knowledge?

Not the exact numbers, but you need to know the approximate locations for each indicator (say weakly acidic, around neutral, or weakly basic). and the colours below, at, and above that pH ofc

But ofc the more details you remember, the better!
When you are in doubt, just learn everything.

When you say weakly acidic, you mean that the pH range is in the weakly acidic range, right?

yeah, the end point
