Ask any JC student what frustrates them most about Economics tuition, and you will often hear the same complaint: the tutor at the front of the room is not the one marking their work. Assignments go out, come back with a grade and a tick, and the cycle repeats without anyone explaining why an argument fell short or how to fix it next time.
This is the quiet problem at the heart of many tuition centres. As class sizes grow, founders and head tutors increasingly hand marking duties to assistants, leaving students with feedback that is generic at best and absent at worst. For a subject like H2 Economics, where success depends on the precision of an argument rather than the volume of content memorised, this gap matters enormously.
Mr Jeffrey Teo of Ace Your Econs built his teaching approach around closing that exact gap. Understanding what makes his method different starts with understanding where he came from, why he teaches the way he does, and how that translates into the structure of every lesson he runs.
A background built on real-world economic thinking
Most JC Economics tutors come from one of two paths: a teaching background with limited exposure to how economic theory plays out commercially, or a strong academic record with little classroom experience translating that knowledge for sixteen and seventeen year olds.
Mr Teo's path is different:
Former banker. Years spent engaging daily with the kind of real-world economic decision-making that most JC textbooks only gesture at, including interest rate movements, inflationary pressures, fiscal policy debates, and market behaviour.
MOE teaching experience. Formal pedagogical training to structure a lesson effectively in line with the official JC curriculum, paired with the subject mastery to make that lesson genuinely insightful.
Over a decade of dedicated JC Economics teaching, refining what works in the classroom rather than relying on a fixed curriculum written once and repeated every year.
When a student struggles to explain why a central bank might raise interest rates despite slowing growth, or why a government subsidy can distort a market in ways that look good on paper but fail in practice, Mr Teo can draw on lived professional experience rather than a textbook paragraph. Students consistently describe his lessons as more relevant and easier to relate to current events precisely because of this background.
Credentials that go beyond a CV line
A tutor's qualifications are often reduced to a single bullet point on a website. Mr Teo's credentials run deeper than that.
He is a best-selling published author of two Economics guidebooks, having put his understanding of the subject and his teaching philosophy into writing that has been reviewed and used by students beyond the walls of his own classroom. This is a meaningfully different bar from simply having taught the syllabus for a number of years. A tutor who can explain a concept in conversation is one thing. A tutor whose explanations have been distilled, structured, and published in guidebooks used by students is another, and it reflects a level of command over the material that goes beyond classroom delivery.
Parents evaluating tutors for their child are often looking for exactly this signal: evidence that the person in front of the classroom has genuine command of the material, not just familiarity with past year papers. You can read more about Mr Teo's full background on AYE's story.
Small classes that make personal attention possible
None of this depth of engagement would matter much if it could not actually reach each student. This is why classes at Ace Your Econs are deliberately capped at around 14 students, rather than expanded to the 20 or 30 student sizes common at larger centres.
At this size, Mr Teo can track each student's individual progress, recognise recurring patterns in their reasoning, and adjust his explanations to the specific gaps a student is showing, rather than teaching to the average of a large room. It is a structural decision, not a capacity constraint, and it is one of the clearest practical differences between Ace Your Econs and centres built around scale.
The ACE framework: a method, not a shortcut
Most students are taught how to write an Economics essay through example. They read model answers, try to imitate the structure, and hope it transfers to an unfamiliar question under exam conditions. The problem is that imitation without understanding tends to collapse the moment a question deviates from the format they memorised.
Mr Teo developed the ACE framework, which stands for Apply, Clarify, Evaluate, to solve this. Rather than handing students a template to copy, the framework teaches a repeatable thinking process for constructing a strong economic argument, one that holds up regardless of how the question is phrased. Students using the ACE framework are equipped to:
Break down unfamiliar questions methodically
Build their analysis logically, step by step
Evaluate with the kind of judgement that distinguishes a strong answer from an average one
Together, these elements reflect something important about Mr Teo's teaching method: he is not interested in giving students answers to memorise. He is interested in giving them tools to think with, tools that remain useful no matter what the A-Level paper throws at them.
Personally marked, every single time
Perhaps the clearest contrast between Mr Teo's approach and the typical tuition centre model lies in how assignments are handled after they are submitted.
At many centres, particularly larger ones, marking is outsourced to teaching assistants or junior tutors as student numbers grow. The head tutor who built the centre's reputation is rarely the one reading a student's actual essay. Feedback becomes standardised, often limited to a grade and a few generic comments that could apply to almost any script.
Mr Teo marks every single assignment himself. There are no teaching assistants quietly handling the workload behind the scenes. When a student submits an essay or case study response, the person reading it, assessing it, and writing feedback on it is the same person who taught the lesson, wrote the guidebooks, and developed the frameworks the student is applying.
This has a direct impact on the quality of feedback students receive:
Mr Teo can identify recurring patterns in a student's reasoning across multiple assignments, something that becomes impossible when marking is split across different assistants each week.
He can connect a weakness in this week's essay to a similar issue from a month ago, and explain precisely what needs to change.
Students are not just told what grade they received. They understand why, and what to do differently next time.
This level of personal involvement is only possible because of the small class sizes described above. It is a structural decision that allows Mr Teo's hands-on approach to remain genuinely hands-on, rather than becoming an unsustainable promise once enrolment numbers climb.
A resource base built over a decade
Frameworks and personal marking are reinforced further by what students can access outside of lesson time. Students at Ace Your Econs have access to:
Over 1,000 hours of recorded lessons, built up across Mr Teo's full teaching career
Ten years of model answers, reflecting the same ACE framework used in class
Mr Teo's own best-selling Economics guidebooks, giving students a structured reference written by the person actually teaching them
This matters particularly for students revising independently or catching up after missing a lesson. Instead of relying on generic notes, they can revisit the exact explanation of a concept as Mr Teo originally taught it, in his own written voice, rather than notes compiled by someone else.
What this difference means for students
The cumulative effect of this approach shows up over time. Students working with frameworks like ACE and MR FAST, supported by feedback from the same tutor who taught the underlying concepts, tend to develop a clearer and more consistent way of thinking through Economics questions.
The outcomes reflect this:
Over 90% of students report a noticeable confidence boost within three months of enrolling
300+ five-star Google reviews (5.0 rating), built on consistent, personally delivered feedback rather than marketing claims

None of this replaces a student's own effort. Frameworks still need to be practised, and feedback still needs to be applied consistently for it to make a difference. But the difference between a tutor who marks every script personally and a centre that outsources the work is not a small one. It shapes whether a student receives feedback that genuinely moves them forward, or feedback that simply confirms a grade they could have guessed themselves.
If you are evaluating tutors for the year ahead, it is worth asking a simple question: who is actually marking the work, and do they understand your child's writing well enough to know exactly where it needs to improve.
