school adviser=学校指导老师/学校导师

The school adviser helped me choose the suitable ones: 学校指导老师帮我选择了合适的课程。

First, I had to think very carefully about which courses I wanted to take. The school adviser helped me choose the suitable ones: maths, English, chemistry, world history, and Chinese. I know that Chinese is a very difficult language, but I hope to be fluent when I graduate. My adviser recommended that I should sign up for advanced literature because I like English and I’m good at it.
