	Yoong Liat  +  277498 Sat, 07 Oct 06 05:35 PM Hi Marius You should do well on the test. You should do well in the test. Should the preposition be 'in' instead of 'on? Or are both acceptable? Yoong Liat Joined on Mon, Sep 4 2006 Veteran Member 6,757 Prepositions

	J Lewis  +  277503 Sat, 07 Oct 06 05:54 PM I prefer "in". If someone says to me You should do well in the test, my immediate interpretation is that the speaker considers I have studied well enough. He could say You will do well, but nobody is ever sure. Also interpretable as advisability, but here I'd be inclined to put it more strongly: You must do well in the test.

If it were advisability, I'd expect to see/hear "you should try to". milky Joined on Thu, Jan 15 2004 Senior Member 3,149 Hume said that if we had perfect or complete descriptive knowledge of reality, we could not, by reasoning, derive a single valid "ought".
