Do you think education should be in your mother tongue?

This question might be more comprehensible for non-English people, but English people are also encouraged to express their opinion.

For someone like me, where there are 4 or 5 languages spoken around, what do you say? My primary education was in my mother tongue. Secondary education was also in my mother tongue; English was a subject introduced then. After that, higher secondary or high school education was in English. And then, engineering was (and is) in English. Yet, mother tongue is mostly used in conversations; English is in academics.

Does learning in your first language strengthen your learning and comprehension? I have been told successful stories of engineers from Europe where they stress on their language.
