That would be totally acceptable. Remember, you are also in a totally different state if you went to the toilet right before the exam. If you drank a litre of water in the morning. If you ate something for breakfast that happens to contain lots of short-chained carbohydrates, providing lots of energy for your brain.

You have to draw the line somewere and coffee is definitely acceptable, if not expected.

Edit:As several comments suggest, your other question about rudeness because of smelling beverages: that's different from course to course, and you will probably have to employ some degree of common sense there. People are usually not bothered by coffee smell as opposed to french fries or the sounds of eating potato crisps. If in doubt, just ask your TA or fellow students before going to the exam.

You might find that your university policy prohibits any beverages except water during exams. Coffee has a strong aroma that can be distracting, especially to the less-awake students who might then crave coffee.

Even if coffee had no aroma, it would still be distracting. A cup of tea or coffee is usually pretty identifiable by sight. If someone walks into my office with a mug of green tea, I usually want a mug of tea myself long before I can smell it. "That guy 20m away is drinking some unidentified hot beverage. Now I want coffee!"

Sure, the consumption of coffee beforehand should be fair and allowed in any country where it's a legal and commonly consumed drug - chances are many classmates drink it too. You still have to have learned the material in order for the coffee to help you remember it. It's just not fair to be distracting to others during a test.

從事計算機科學工作，並查看該部門的咖啡因飲料消費情況，我想知道：是否可以沒有工作？認真地說，您被合法地允許購買這些東西，並且只要您的大學沒有任何禁止的規定，就可以這樣做（編輯：，只要您符合“社會規範” ）。有些人會吃葡萄糖/葡萄糖或做其他他們認為會幫助他們的事情。我猜每個人都有自己的儀式。

服用其他藥物才能更好地學習是一個完全不同的故事，但是在這裡，只要您的大學允許，我不會遇到任何問題。因此，這既不粗魯，也不是任何形式的作弊。

在我的課堂上，學生們總是把咖啡帶到我的考試中。當我必須參加清晨的考試時， I 經常會帶一壺咖啡和紙杯，並免費為學生提供杯咖啡，以幫助他們提高成績。

關於是否有可能使用毒品“作弊”，存在著深刻的哲學問題。歸結為一個人是否認為“欺騙”是由制度規則所定義的，還是一種超出書面規則的道德違規行為。

大多數實際的作弊政策都禁止在考試期間共享或接收信息，但沒有提及提高性能的藥物（例如Adderall）。一些大學確實有關於濫用處方藥的政策，例如杜克大學的政策。但是我大學的政策沒有提及提高性能的藥物。儘管擁有未開處方的處方藥可能在某種程度上是非法的，但這並不違反我學校的任何學術“作弊”規定。

我懷疑任何學校都有禁止咖啡因的規定。請注意，杜克（Duke）聲明僅提及處方藥物-當然是故意的。在美國，除了少數宗教團體外，喝咖啡是提高注意力的一種方式。

您的學校可能更擔心的是，如果您灑了咖啡，會擔心會亂成一團，而不是擔心喝咖啡會帶來什麼好處。因此，除非有人要求您停止，否則您不必擔心。

我認為您問題中的重點可以更明確地表述為：

是什麼決定考試中哪些優點是公平的，哪些是不公平的？

為了公平的利益而走極端：考試那天不生病嗎？不餓作弊嗎？在作弊前不熬夜嗎？參加每個講座和學習會公平嗎？學習考試公平嗎？比同學還聰明嗎？始終將正確答案標記為公平嗎？是不是很幸運，並且考試的題目是關於您碰巧非常有經驗的（經驗豐富的數據庫程序員的數據庫問題）？

所有這些顯然都很好。但請考慮另一個極端：

考試公平期間吸煙嗎？服用Adderall是否公平？考試前做可卡因公平嗎？入侵講師的計算機以獲取答案是否公平？操縱助教誘騙他們向您透露答案是否公平？帶上備忘單或電話公平嗎？讓其他人和您一起參加考試公平嗎？

這些在質量上與上一組沒有什麼不同。當然，有些以非法（黑客攻擊）而著稱，但許多在除考試環境外的所有方面都提高了績效（在手邊有參考資料，在線查找您不了解的內容，與同行合作）。

我想通過以下方式解決這一問題：考試不是精英。關鍵不是要執行某種平等原則，也不是“讓伴郎贏得勝利”。考試是課程的一部分，課程的目的是使學生精通課程材料。考試是學生獨立學習和準備的目標。

如果您同意這一點，那麼什麼是公平的問題就變得微不足道了：指導老師允許“公平”。 “他們認為有助學習的任何行為。

例如，對於沒有太多時間學習的學生來說，連續學習幾天可能是不公平的，但是鼓勵學生學習有益於學習，因此講師將其視為公平並予以認可。

另一方面，事先竊取考試題是“做好”考試的一種極其有效的方法，但您不僅不會以這種方式學到任何東西，如果您被抓住並受到懲罰，可能會對您的未來職業造成嚴重後果。盜竊問題是一種使考試成為不正當動機的機制。因此，講師試圖通過專門禁止這種機制來糾正這種情況。我認為，這種被禁止的機制被稱為“不公平”（似乎意味著某種平等主義或司法目的），這是語言的產物。

回到您的問題：

在測試期間喝咖啡因對我來說公平嗎？

讓我們接受這樣的前提：喝咖啡會提高您的表現（我對此表示懷疑）。

這是否有利於學習過程？有一個很小的積極影響-考試期間您的大腦表現更好，這意味著當您在考試中被迫使用某個概念時，您將更有可能真正抓住一個概念。

它是否有助於不正當動機？可疑。

• 如果咖啡因對精神發育有很大幫助，則學生可能會在上課或學習期間開始飲用咖啡因，這意味著他們的學習將得到增強。
>
• 如果他們僅在考試期間喝酒，與其他學生相比，他們的分數就會稍微提高。但是效果很小，而且具有自我抑製作用：事實證明，咖啡越有效，就會有更多的學生開始喝咖啡，而無論如何，每個人最終都將處於平等的地位。
• 咖啡的氣味可能會稍微不利於其他學生，如果考試按曲線評分，這對您的成績會有很小的積極影響。但是，這種影響很小，如果有任何學生有其他感覺，他們總是可以抱怨並要求您刪除有問題的飲料。

總的來說，似乎有一些積極的方面負面影響很少，但都很小。唯一有意義的激勵措施是咖啡店的業務-但這不會減損學習過程。

另一方面，有些人喜歡喝咖啡，這會使他們在咖啡店裡感到更舒適考試，如果讓他們相信自己可以控制自己的表現並以自己的喜好“堆砌甲板”，那麼心理動機可能會有助於對整個課程產生更積極的態度。總而言之，當您嘗試教別人某事時，如果他們身體舒適而不是不舒服，可能會更好。因此，我認為不應認為這是不公平的或被禁止的，除非學生非常笨拙並不斷地倒咖啡，通過空杯子亂扔垃圾或以其他不可接受的方式處理咖啡。

附錄中包含更多具有“核心”性能的藥物，可能並非如此。例如，講師很可能會反對服用Adderall之類的藥物（儘管這很難執行），因為這會激勵濫用這些藥物。與通常不認為是有害的咖啡因濫用不同，濫用Adderall具有嚴重的有害後果。

One of my students admitted to me that he took a harmless and side-effect free sugar pill before a stressful exam in order to benefit from the placebo effect, which placed him in a different state of mind to his cohort, unfairly enhancing his cognitive capabilities. Needless to say, he was summarily dismissed.

I am a caffeine abstainer. I don't drink coffee because I can't stand it. The caffeine in the coffee might give you an advantage over me, but it would be the same advantage in the workplace (where I also don't drink coffee). So I think it is fair.

The day I took a standardized test that helped determine my academic career, the weather was really hot. Everyone showed up to the test center wearing summer clothing. I was the only one to bring a jacket in my bag. The test center cranked up the A/C and I put my jacket on. Was my comfort cheating?

At the university I went there where plastic cups available at the entrance and if you wanted coffee or tea you could take a cup and put it on your desk if you wanted coffee and upside down on your desk if you wanted tea. Then when the test started a coffee lady would walk by and fill your cup if you had one. This leads me to think that it is acceptable (if not commonplace) to have coffee in the exam.

This would only be unethical if you'd be gaining an advantage that is unavailable to other students. For example, if coffee would be prohibited, but you'd use it despite of that, or if it were too expensive for others to obtain. But as long as caffeine is socially acceptable, readily available for everybody and allowed at the exams, it's a fair choice for every body to use it or not.

My short answer is Yes. You can drink as much coffee as you want.

I've studied in 4 universities and had many exams in my academic life. I've systematically experimented different ways to boost my performance in exams. I've experimented with sugar-rich snacks, coffee, prayers, meditation, and a few more. I know my experiments would not stand scientific scrutiny and you should take them with a grain of salt but they gave me an insight into what actually matters.

The difference coffee made in my exams was insignificant. I can assert the same thing about effects of chocolate, sugary drinks, meditation, and prayer. The only thing that seemed to be directly correlated to my performance was amount of practice before exam. Whenever I locked myself in the library and studied the course material hard, I did well in the exams regardless of anything else. I also did poorly in easy exams when I didn't prepare.

So drink coffee with no guilt because you are not manipulating your performance.

編輯：

只要公開帶上咖啡杯，無論是否是個好主意，您都會在工作人員和學生的臉上看到。

*這並不不公平，因為（1）任何人都可以做到，（2）這不是競爭。

*這不是在作弊，如果允許的話，其效果肯定是最小的。

為什麼公平性完全進入方程式？您將根據您的表現進行評分，而不是相對於其他人。這不是競爭，而是個人評估。此外，任何人都可以隨意喝咖啡。

在任何情況下，我都不認為咖啡或考試中服用的任何其他藥物會產生很大的影響。

When there are thousands of ways to be proficient at any given subject, hundreds of ways to learn and execute the skills required to be successful at any given subject, and a million ways to fail... Is it fair to measure a student's proficiency with only a narrow sliver of a window into said student's ability provided by a paper test in the first place?

I say absolutely not; And limiting the student's scope of success to what one person (or few people) think is the 'correct' application of a concept is setting education back hundreds of years, and is entirely unfair to the students and society at large.

That being said, do what you have to do to get out of that trap so you can move on to the real world where you're going to be applying those skills and concepts as a matter of survival-- where you're free to drink as much coffee as you want, and use as many calculators and references as you need to get the job done. Don't ignore the lessons! Just get through the tests without worrying about fairness- the world isn't a fair place anyway, and you're the only one responsible for being good at what you do; Not the education system; So who cares if it's fair that you drink coffee? As long as you pass your tests and enter the professional world as a reliable quality producer of goods and services.
