You shouldn't have finished the core courses of your major, so it's normal to be uninterested. There is also the problem of basic courses. Basic courses are generally difficult, but not so difficult in real projects. They all used a little. I think it's mainly because there is too much content and too little study time, and you don't fully understand it. Basic courses will have an impact on your professional courses in the next two years, but the problem is not big. The key is that professional courses will give. I hope you learn math and English well (this is true, you must listen to it). The core of professional courses is to learn well: three courses, signal and system, analog electricity and digital electricity, are the most important and get twice the result with half the effort. You can herd sheep in other classes. In fact, these three courses all have certain skills.
Signal: It is a mathematical tool, focusing on three transformations (undergraduate requirements)
Electricity metering: master the use of key chips and basically master the methods of electricity metering (Karnaugh map and the like are concrete methods, so it is no problem to be careful), and electricity metering is the simplest.
Analog electronics: it's more difficult. It is no problem to memorize several circuits. Analog electronic undergraduate mainly recites; Such as amplifier circuit, differential, power amplifier, operational amplifier, negative feedback and so on (it doesn't matter if you haven't learned it)
Speaking of postgraduate entrance examination, in fact, there are many kinds of postgraduate entrance examination for electronics, and almost all universities have master's degrees, so the difficulty of postgraduate entrance examination is relatively small. Due to the saturation of economic and management personnel, it is quite difficult in the postgraduate entrance examination army and the score is relatively high. When you arrive, you will find that our major is actually a lot of fun when you take a professional class in junior year.
However, our professional postgraduate entrance examination has high requirements for mathematics, but you will have time to review from the third year of high school, so don't worry; In the future, you are likely to take one or two of the above professional courses, depending on the school you apply for.
It's messy to write so much. I just hope you can calm down and study hard. There are many choices in the future, but first you have to make all kinds of preparations. Many famous economists and managers are transferred from engineering. In fact, the most ideal undergraduate course is engineering, which can help you build a more rational and rigorous thinking and greatly promote your future development. After all, the earth is not blown out, and fantasy is useless. It's still a little early to talk about postgraduate entrance examination in grade two. It is very important to learn this year's class well. Work hard and wish you success.
