Yserbius123,
Sorry I’m a bit late, but I would like to set the facts straight regarding your comments on Lubavitch chinuch:
The Lubavitcher Rebbe was vehemently opposed to studying ANY limmudei chol (English, math, science) at any point of the chinuch system.
In the chadorim, he only allowed the minimum limmudei chol if there was a risk that the students would otherwise go to less frum mosdos.
For this reason, many chabad chadorim teach basic English, while many do not teach English at all (such as Oholei Torah in Crown Heights, which the Rebbe founded).
When it comes to mesivtos, virtually no chabad mesivtos teach limmudei chol (there may be one or two small ones out of more than 40-50).
