    Is Electrical Engineering Hard? 【Facts】

    For me, the main problem was that there was more theory than practical in our curriculum. Even in the labs, experiments were done in groups. As a female where the majority were males, I was kinda cornered. At that time there were not so many online tutorials. It was not easy to buy electronic...
