It is suggested that the questioner choose micro-solid, after all, micro-solid is much higher than photoelectric. Especially in materials. However, one advantage of taking the photoelectric test is that it is easy to get low marks. It is suggested that those who have not pursued can choose.

Here's only one thing to correct downstairs.

* Optoelectronic enrolls graduate students majoring in materials, limited to optoelectronic materials. Among them, the research directions of professional courses are as follows.

However, I suggest that this is just your retreat after failing the micro-solid exam.
