如果你對於在英國攻讀學位感興趣，那麽你一定聽說過英國G5大學。G5大學指的是英國的五所頂級大學，它們在學術研究和教學方面享有盛譽。在本篇文章中，我們將一起探索英國G5大學以及入讀這些學府的英國G5碩士升學路。

那麽，到底哪些大學被稱為英國的G5大學呢？它們分別是：牛津大學（University of Oxford）、劍橋大學（University of Cambridge）、倫敦政治經濟學院（The London School of Economics and Political Science, LSE）、倫敦大學學院（University College London, UCL）和倫敦帝國學院（Imperial College London）。這些學府不僅在英國乃至全球享有聲譽，也是許多學生夢寐以求的目標。

那麽，如果你想要入讀英國的G5大學攻讀碩士學位，以下這些步驟和建議，幫助你走上升學之路。

如申請熱門學科 應提前準備個人自薦信

G5大學提供了廣泛的學術領域和專業選擇，從人文科學到自然科學，從社會科學到商學。你首先應仔細研究每個學校的課程目錄和要求，找到與自己興趣和職業目標相符的專業。而入讀G5大學的申請材料通常包括個人自薦信（Personal Statement）、推薦信、學術成績單和英語語言能力證明（如雅思或托福成績）。而個人自薦信是你展示自己獨特背景、學術興趣和適應能力的重要機會。確保提前準備和完善這些材料，以增加入讀G5大學的競爭力。假如想入讀英國大學的熱門學科，如醫科、獸醫、法律等，不少人甚至會提前數月開始準備。

不少G5大學可能需要進行個人面試作為申請的一部分。申請人應提前準備並練習面試技巧，展示自己的學術能力和適應能力。在五所大學中，除了 LSE 大部分學科沒硬性要求面試之外，其餘四所大學的熱門學科都需要申請人參加網上面試，有某部份學科甚至會要求學生回答特定問題並自行錄製影片上傳。亦有部份學科會要求申請學生即場在面試中進行短文寫作，以考核學生的學術分析能力和個人思考能力。因此，學生假如希望攻讀G5大學的碩士課程，平日緊記要提升英語口語能力。

攻讀碩士學位可能需要一定的經濟基礎，但千萬不要灰心，許多G5大學提供獎學金和資助機會，幫助學生減輕經濟負擔。在申請過程中，注意尋找並申請適合自己的獎學金計劃，並準備好相關的申請材料。

對於香港的學生而言，英國牛津大學的羅德學士獎學金每年均有資助香港學生就讀研究生課程；香港賽馬會獎學金每年亦有提供 3 個名額，全數資助學生在牛津大學攻讀任何碩士或博士學位期間所需的學費、學院費及生活費。而劍橋大學亦設有蓋茨劍橋獎學金，資助來自英國以外國家，攻讀劍橋大學碩士或博士研究生的優秀學者。

如想了解其他學校的獎學金，請自行留意不同院校的網頁。

申請英國G5大學前 宜先研究學校所在城市

在申請入讀G5大學之前，建議學生最好花些時間了解學校和所在城市的文化、環境和生活成本。每個學校都有其獨特的特點和優勢，選擇適合自己的學校將有助於你的學習和生活體驗。入讀英國G5碩士是許多學生的夢想，假如大家想了解更多英國留學資訊， 歡迎與 Cyclopes 聯絡。

If you are interested in pursuing a degree in the UK, then you've undoubtedly heard of the UK G5 universities. The G5 universities refer to the five elite universities in the UK, which are renowned for their academic research and teaching. In this article, we will explore the UK G5 universities and the path to pursuing a Master's degree at these esteemed institutions.

So, which universities are considered the G5 in the UK? They are: the University of Oxford, the University of Cambridge, the London School of Economics and Political Science (LSE), University College London (UCL), and Imperial College London. These institutions are not only prestigious in the UK but also around the world, and they are the dream of many students.

If you are aiming to enter one of the UK's G5 universities for a Master's degree, the following steps and suggestions will help you on the path to further education.

G5 universities offer a wide range of academic fields and specialties, from the humanities and natural sciences to social sciences and business. You should first carefully study the curriculum catalog and requirements of each school to find the specialty that aligns with your interests and career goals. The application materials for entering a G5 university typically include a Personal Statement, letters of recommendation, academic transcripts, and proof of English language proficiency (such as IELTS or TOEFL scores). The Personal Statement is a critical opportunity to showcase your unique background, academic interests, and adaptability. Ensure that you prepare and perfect these materials well in advance to increase your competitiveness for admission into a G5 university. For popular subjects such as medicine, veterinary science, and law, many people even begin preparing months in advance.

Many G5 universities may require personal interviews as part of the application process. Applicants should prepare and practice their interview skills in advance to showcase their academic abilities and adaptability. Among the five universities, except for most subjects at LSE which do not strictly require interviews, the other four universities require applicants for popular subjects to participate in online interviews. Some subjects may even require students to respond to specific questions and upload a self-recorded video. There are also some subjects that require applicants to write short essays during the interview to assess their academic analysis abilities and personal thinking skills. Therefore, if students wish to pursue a Master's program at a G5 university, it is essential to improve their English speaking skills regularly.

Pursuing a Master's degree can require a significant financial foundation, but do not be discouraged; many G5 universities offer scholarships and funding opportunities to help students alleviate the financial burden. During the application process, be sure to look for and apply for scholarship programs that suit you, and prepare the relevant application materials.

For students from Hong Kong, the Rhodes Scholarship at the University of Oxford provides support every year for Hong Kong students to attend graduate courses; the Hong Kong Jockey Club Scholarship also offers 3 spots annually, fully funding students at the University of Oxford for any Master's or Doctoral degrees covering tuition, college fees, and living expenses. Cambridge University also offers the Gates Cambridge Scholarship, funding outstanding scholars from outside the UK to pursue Master's or Doctoral research at the University of Cambridge.

For information on scholarships from other schools, please check the respective university websites.

Before applying to a G5 university, it is advisable for students to take some time to understand the culture, environment, and cost of living of the school and its city. Each school has its unique characteristics and advantages, and choosing the right one will enhance your learning and living experience. Pursuing aMaster'sdegree at a UK G5 university is the dream of many students, and if you want to learn more about studying in the UK, feel free to contact Cyclopes.

在香港及亞洲各地，家長們無止境地追求讓孩子進入頂尖大學——但畢業後的去向又是怎樣的？令人驚訝的是，根據CTgoodjobs HK於2020年的報告，47%的香港大學畢業生最終從事與所學專業毫無關聯的工作。讀法律的人成為了科技創業家，主修生物的學生轉行做市場營銷。儘管如此，追逐「名牌大學」的動機卻絲毫未減。 

這反映了一個令人痛心的事實：我們把教育視為目的地，而不是過程。教育本應是一個指引方向的羅盤，但我們卻在潛意識裡將其簡化成一個「獎盃」。虎媽虎爸們執著於常春藤名校的學位及完美的成績，卻鮮少反思一個更重要的問題：這些真的能令我的孩子擁有充實且有意義的職涯，活得精彩嗎？ 

若你的孩子將來在一份自己不喜歡的工作上耗費數年甚至數十年，那進入一所「好大學」的意義何在？這樣的教育是否真的值得？請記住，教育應該是賦能的，而不是設限的。大學學士四年，但其後的職涯卻可長達四十年。因此，是否升學規劃理應從「職涯自我探索」開始。&nbsp;

這不只是數據層面的議題。2018年，Amazon 創辦人貝佐斯（Jeff Bezos）在一次啟發人心的演講中曾提及過：&nbsp;

「我們每個人都有熱衷的事，但那不是由你選擇的，而是它主動召喚你的。關鍵在於，我們是否有意識地去留意並尋找它的存在。」&nbsp;

「一旦找到屬於自己熱衷的事，那便是人生最寶貴的禮物，因為它不僅賦予我們前進的方向，更賦予我們存在的意義與目標。」&nbsp;

那麼，我該如何發掘真正屬於自己的人生方向及職涯使命？我又該如何找到那些真正能驅動我、激發我前進的內在動力？&nbsp;

自我探索的科學：RIASEC 模型與大數據應用

在現今競爭激烈且快速變動的職場環境中，精準了解個人的性格特質與職涯傾向，已成為制定升學與職涯規劃的關鍵一步。SDS（Self-Directed Search，自我導向探索測驗）便是一項經過數十年心理學研究驗證，並結合現代大數據分析技術的專業工具。該測驗以 RIASEC 六型人格職業分類理論為基礎，將人們的興趣與潛能分為以下六大類型：

這套系統性架構不僅有助於學生認識自身核心特質，更在以下幾方面展現出高度實用性與前瞻性：

因此，科學化的性格職涯分析不僅是一項輔助工具，更是一個協助學生在人生早期作出明智抉擇、減少錯配風險、提高職涯幸福感的重要基石。&nbsp;

或許我們該停止單向地要求孩子「讀法律」、「讀醫科」，或「因為高薪而選讀金融」，而是該問一句：孩子夢想中的學科，是否真的與他們的性格優勢及核心價值觀相符？&nbsp;

SDS 測驗能幫助學生明確這些特質，避免因選錯大學科系而耽誤甚至扭曲他們的40年職涯。&nbsp;

不是放棄成績，而是重新定義成功

我們的目標，並不是否定名牌大學及良好學業表現的影響力，而是希望你多維度思考「成功」的真正意義。我們相信，升學與職涯規劃不應僅僅以分數和名校為唯一指標，而是應該從孩子的個人特質、興趣與價值出發，尋找最適合他們長遠發展的方向和潛能。如果孩子未來數十年都從事一份無法投入熱情、無法展現所長的工作，那麼即使當初進入了名校，也可能只是換來一段與幸福背道而馳的職業生「捱」。&nbsp;

與其讓選科與升學變成一場賭博，我們更相信透過科學化的工具與數據分析，可以為孩子帶來更明確的方向。立即為子女預約參加職涯測驗，配合我們內部的大數據職涯配對工具，我們將協助學生：&nbsp;

在人生與職場中，活得精彩，永遠比勉強生存來得重要——每天如此，始終如此。&nbsp;

Across Hong Kong and much of Asia, parents relentlessly strive to secure places for their children at top-ranking universities. Yet one must ask—what happens after graduation? According to a 2020 report by CTgoodjobs HK, 47% of Hong Kong university graduates end up working in fields completely unrelated to their degree. Law graduates become tech entrepreneurs; biology majors pivot to marketing roles. Still, the pursuit of so-called “prestigious universities” remains as fervent as ever.  

This reflects a disheartening reality: we have come to treat education as a destination, rather than a journey. Instead of serving as a compass that guides direction, education has subconsciously been reduced to a trophy. Tiger parents often fixate on Ivy League degrees and flawless academic performance, yet seldom reflect on a more fundamental question: Will these choices truly help my child lead a meaningful, fulfilling career and life?  

If your child spends years—or even decades—in a job they dislike, what is the real value of having entered a "top university"? Was the education truly worthwhile? Education should be a source of empowerment, not limitation. A typical undergraduate degree spans 3-4 years, but one’s career may stretch over four decades. It is only logical, then, that higher education planning should begin with career self-discovery. 

This issue goes far beyond statistics. In a 2018 speech, Amazon founder Jeff Bezos shared this insightful perspective: 

“We all have passions, and you don’t get to choose them — they pick you. But you have to be alert to them. You have to be looking for them.” 

“And when you find your passion, it’s a fantastic gift for you. Because it gives you direction. It gives you purpose.” 

So how do I discover my true passion? How do I identify what drives me and fuels my motivation?

The Science of Self-Discovery: RIASEC and the Power of Big Data

In today’s fast-changing and competitive world, understanding one’s personality traits and career inclinations has become a vital first step in any meaningful academic or career plan. The Self-Directed Search (SDS) is a professional, data-backed assessment tool grounded in decades of psychological research and enhanced by modern big data analytics. It is built upon the RIASEC model, which categorises individuals into six core personality types based on interests and aptitudes: 

This structured framework not only helps students identify their personal strengths but also proves highly effective in several practical areas: 

Rather than placing pressure on students to apply for degree programmes that are traditionally associated with professional qualifications or high-income careers, a more constructive approach would be to ask: Does their chosen subject truly synchronise with their individual strengths and core values?&nbsp;

The SDS enables students to explore these dimensions early on, helping them avoid being derailed by a 3-4 years degree mismatch that could negatively impact a forty-year career. 

It's Not About Abandoning Academic Excellence—It's About Redefining Success

Our message is not to downplay the value of strong academic results or the advantages of entering a reputable university. Rather, it is to encourage a redefinition of success. We believe that educational and career planning should not be based solely on grades or university rankings, but instead stem from a deep understanding of a student’s personality, interests, and values. If a child ends up spending their entire working life in a job that lacks passion or purpose, then even the most prestigious degree may ultimately lead to a career of quiet dissatisfaction. &nbsp;

Instead of letting subject selection and university admissions become a gamble, we believe that science and data can offer clarity. Book a career assessment for your child today. Using our in-house big data career matching system alongside the SDS test, we help students: 

In life and in work, to thrive is always better than to merely survive—every day, every time.
