一天来了。您已经在HSC中幸存下来，现在您开始按顺序获取UAC申请，并看到有关科学专业的一些信息。您不太确定只有一件事。
您到底想做什么？
This is probably about where you’re at right now, so when you’re looking at degree choices and you think“如果写在斯瓦希里语中，我可能会更多地了解这一点”，，，，it’s just more stress you do not need.
您可能想学习生物学，但是您的梦想uni只能提出“科学学士学位”（BSCI）。这很正常 - 大多数科学专业的学生都参加了BSCI。区别在于您选择的科学专业。
Hang on, what’s a major?
您可能认为大学提供学位。这是正确的 - 但比这更微妙。What universities really offer are “units”，或单年学科。
If you complete a certain combination of units, that’s what entitles you to a degree.
在某些大学（例如我自己的UTS），学位课程具有非常紧密的结构化课程。您必须完成总共24个单位，没有选修课，并且他们已经为我们决定了订单。
但是，大多数大学采用更自由的方法。每个单元都是独立构建的，学生只需要完成正确的单位组合即可获得学位，以任何顺序和任何速度。
那么，这如何帮助我们理解专业？
您将入学的“学位”是BSCI，为了获得BSCI，您必须完成一些单位。
These units are generally a chemistry unit and a maths or stats unit and perhaps some others depending on the philosophy of your university.
但这仍然使您有20个单元可以完成，然后才能获得学位。
从理论上讲，您可以做自己喜欢的事情并仍然获得BSCI - 但这不会在另一端找到工作，也不有利于任何事情。您会刮擦很多东西的表面，但要抓挠您的细节。
因此，大多数人要做的是选择“专业”- 一定的组合组合，以专门为特定领域的学生知识而设计。
这意味着您的学位将阅读BSCI（*在此处插入专业*）rather than justBSCI，，，，and, of course, you’ll have a more specialised and marketable skill set.
好的，我有什么样的选择？
Obviously, the specifics change from uni to uni.您几乎可以在任何地方都看到的四个科学主要选择是物理，化学，生物学和地球科学。
在这四个之间，您几乎涵盖了科学的所有利基市场。
Most universities also offer Mathematics and Statistics majors through their science faculty, as well as computer science.
The one thing about computer science is that most universities also offer IT degrees serving a similar purpose. It’s outside my field of expertise, so you”ll have to decide for yourself which is to your liking.
Of course, there’s no shortage of more specialised choices for your science major.
诸如生物技术，药理学，天文学，环境监测，古生物学，纳米技术，神经科学/心理学甚至是食品科学等事情，这只能研究悉尼四所主要大学。
想象一下那里还有什么！
这都是一种寻找适合的东西your needs.
从AT挑选科学专业UNSW，，，，UTS，，，，USYDand麦格理如果您渴望获得更多信息。
Keep in mind Science faculties offer courses that aren’t a BSci, but instead have a more specific title.
My degree, for instance, is the “Bachelor of Applied Chemistry in Forensic Science” at UTS, which isn’t listed as a science major (in fact, it’s not listed anywhere since it technically doesn’t exist anymore, but you get my point).
How do I even begin to choose?
首先，深呼吸。在选择专业之前，您几乎总是至少拥有一个完全核心的学科。
You can do as many as two years before choosing a science major at most universities.
笔记：You can get a BSci without a major – by this I mean that, after two years, adding a major to your program will mean extending your degree past the projected time frame, or occasionally having to re-apply for a position in the program.
However, the most common time to choose a science major is after first year,so you don’t have to know right now.
The general majors (physics, chem, bio and earth sci) aregreat if you’re unsure about long-term goals。
They don’t lock you down too much and leave plenty of room to specialise with further study. They’re a good choice if you just want to go with the flow and let the wind take you wherever it will.
It’s also pretty easy to switch between theseif you decide you’ve made the wrong choice, since some of them with share a fair bit of material.
In particular, it’s easy to move from physics to chemistry and from biology to earth science. It’s a little harder to do those same changes the other way, and then harder again to do any other change, but still pretty readily doable.
On the other hand,if you know what fires you up, there’s not a drop of shame in pursuing your passion from day onewith a more specific major.

Anything else I should know?
Just a couple more things.
A Double Major
我敢肯定，您熟悉双专业的概念，或者至少能够弄清楚它。
Don’t feel like you have to choose between two things- 参加双专业，如果您想出一个是他们真正想要的，那就是它们，另一个。
如果没有专门针对您的梦想，您可以将两个混合在一起制作一个新的，kind of like making a new coloured paint.
Maybe, if you’re into robotics but can’t find a good course for it, combine computer science with biotechnology.
Mixing food science and psychology may not seem like the most natural pairing, but the diet industry would kill for someone with that skill set.
Be aware though,this does extend your degree.
Taking a double major generally adds an extra year, and a double degree an extra two.
So if you want to take a double degree with one double major, that’ll be six years – if you love it, that’ll seem like nothing at all, but it’s also 3 years of work experience you don’t have that someone else does.
这没什么可害怕的，但这是值得考虑的事情。
A Minor
Depending on your university,您也许也可以参加“子劳动”，，，，sometimes colloquially called a minor.
这只是一个较小的单元组合，与您在该领域的主修相比，您在该领域的技能较低，但通过工作场所培训或进一步学习为您提供了良好的基础来学习和改进它。
It’s a good solution if you want the benefits of the double major, but only want to spend 3 or 4 years at uni instead of 5 or 6.
Just remember to put yourself first when you make your decision – don’t prioritise what your parents want, or what you think you should do. Do what you believe you want.
Hopefully you feel better equipped to plan out your next step now with this information behind you.
The most important thing to remember is thatno decision is irreversible.实际上，你们中的许多人将在21岁时研究生大学 - 目前的退休年龄为67岁，但到您和我到达那里时可能会更高。
这是整整46年或更长时间。不要欺骗自己，以为您必须花它们所有的事情，就像18岁时那样想要做的事情。
