I think most or all have English classes in school, but in addition to the drop-out/absenteeism even those that attend these classes often don't end up learning much of the language itself as the teachers either have little training and/or pedagogical knowledge or apply the sanskrit approach: a complex near-dead language that's taught through memorisation of grammar rules, similar to Latin.
