推荐答案

在参加考试时，我发现做BEFOREHAND之前需要做的一些工作通常比在做事时问别人要好.

好吧，想象一下我们会为您回答这些问题，这是否会使知识通过某种神经网络/大脑渗透作用进入您的脑海?

不，不是，所以您通过考试而又不知道有关该主题的胡言乱语，然后就去参加面试.

现在，在采访中，他们会问您问题，您就像大灯下的兔子一样凝视着他们，然后眼泪f着建筑物，因为您意识到自己应该完成这项工作.

因此，实际上，我们在不回答您的问题方面很有帮助.

别去研究年轻人，学习，这是这里其他人所做的.

任何人如果想在生活中取得成功，就是要做的事情.

附言，祝您考试顺利.

When I sit exams, I find that doing some of the work required BEFOREHAND is often better than having to ask people whilst doing them.

OK, so imagine we answer them for you, does that put the knowledge into your head via some neuralistic web/brain osmosis?

No, it doesn''t, so you pass the exam without knowing bollocks about the subject and then you go for an interview.

Now at the interview they will ask you questions and you will just stare at them like a rabbit in the headlights, and then flee the building in tears as you realise that you should have done the work.

So in fact we are being helpful in not answering your questions.

No go study young man, and learn, it is what everyone else here did.

It is what anyone does if they wish to succeed in life.

PS, Good luck with the test.

您昨天尝试过此方法，希望我们可以帮助您通过面试.请您自己研究-Google会为您提供帮助.

You tried this yesterday in the hope that we can help you pass your interview. Please do your own research - Google will help you.
