I do not agree with most of modern education, I my mind the thing to concentrate on are Mathematics Physics and the Avi Ezri of Rav Shach  But I would also agree to learning Mechanical Engineering -which after all was what my father father majored in in school. But you might ask, "What if I am not talented in Math?" To answer that question I have mentioned that to some Rishonim, learning Physics and Metaphysics is in the category of learning the Oral Law.  [These would be Rishonim that were going by Rav Saadia Gaon Ibn Pakuda and the Rambam] That means that it is a mitzvah to learn them whether one i talented or not.
