Usage of Where

[Blue_Skies]

In MGMAT guide,it's mentioned that where should be used only for places. The following example is given : Algebra 2 was where i learned to factor.

I am not convinced that this sentence is incorrect. Can't where describe logical place such as a classroom in this example ? Can somebody please help me understand ?

THanks!

Hi,
As you are following MGMAT guides,I am pasting the below text from the same book that will help you with the correct usage of where:

The pronoun where can be used to modify a noun place, such as area, site, country or
Nevada. Where cannot modify a "metaphorical" place, such as condition, situation, case, circumstances,
or arrangement. In these cases, use in which rather than where.

Wrong: We had an arrangement WHERE he cooked and I cleaned.
Right: We had an arrangement IN WHICH he cooked and I cleaned.
