What does this mean

[newgrad1234]

I had emailed a professor to express my interest in being a representative on the school council.

She says she will need to wait until Thursday to see if other students are interested.

If there are none, then I will get the position.

What does this mean? Do I need to make extra effort (i.e. go to office to discuss)?

It means exactly what it says. Sounds like at the deadline for expressing interest is on Thursday and therefore a decision can't be made before then. I don't think you need to do anything now. I would just write back to thank the professor, and express again my excitement and enthusiasm at the prospect of getting this position, and how much I look forward to hearing from her on Thursday.
