The bigger the topic, the better? No, their experience after writing is the relevant point of the paper you choose. The smaller the paper, the more detailed it is, because although you choose a bigger topic and can write a lot, you can't write anything.

Topics have great advantages. For example, if you study economics or accounting and finance, write a topic. On the influence of bank deposit interest rate on the stock market, this topic is too big. You can write a lot, such as what factors have changed the stock market, what policies have affected this interest rate of banks, and what is the relationship between the two? You seem to think it's big and the framework is easy to write, but in the end you find that what you write is what others already know, and your own subjective opinions are few, so you can't write anything innovative, which is not what the teacher wants.

The teacher wants to see your own views on some fields or points of this major through your paper, and you have written so many basic knowledge introductions before, just to get your own views. I can have a novel idea when writing a smaller one, but the idea of writing stocks, futures and finance, which are common to everyone, is almost fixed. The predecessors have developed for decades or even hundreds of years. Why do you think that studying for three or even four years is better than so many Nobel Prize winners? You can't write such a big topic.

Choose a topic with a smaller topic and a smaller scope, and you can find your own point of view. Moreover, there are not so many people studying this field, and you can have your own point of view, but you should write management ideas and develop your own management ideas. Sorry, you haven't reached that height yet. Your views on management thought have been written before. Do you agree or disagree? This is not what the teacher wants. Do you agree or disagree?
