Tip 1: Every "explain" or "describe" question needs two linked steps
One mark goes to the initial point. The second mark goes to the development of that point — and it must be directly connected, not a separate fact added alongside it.
This is where most marks are lost on the shorter questions. A student writes a correct statement, stops, and moves on — unaware that a single sentence cannot achieve full marks on a two-mark explain question regardless of how accurate it is.
The fix is mechanical once the habit is in place. After every point you make, add a clause beginning with "which means that..." or "so that..." or "because..." and complete the thought. "Heuristic detection analyses the behaviour of a program, which means that previously unknown malware can be identified without needing a matching entry in a virus definition database." The first clause is the point. The second clause is the development. Together they earn both marks. Separately, the first earns one and the second earns nothing if it stands alone without connection to the first.
Before moving on from any explain or describe question, count the marks available and count the linked steps in your answer. If they do not match, add the development.
Tip 2: Precise terminology is not optional — it is the answer
We are specifically looking for subject-specific language, and general terms that approximate the correct answer without landing on it will not be credited in the same way.
The two areas where imprecision costs marks most reliably are storage and networking. "Memory" in IT has a precise meaning — it refers to RAM, the temporary volatile store used by the processor during operation. Using "memory" to mean a hard drive or an SSD is technically wrong and signals to the examiner that the distinction has not been learned. Secondary storage is secondary storage — name it as such.
In networking, "cable" is not sufficiently precise when the question distinguishes between transmission media. Fibre-optic cable carries light signals and behaves entirely differently from copper cable carrying electrical signals — they have different bandwidth capacities, different susceptibility to interference, and different installation requirements. Name the specific type. Similarly, "wireless" is not a transmission medium — microwave, radio wave, and infrared are. Use the specific term the question context calls for.
When revising, go through your notes and replace every general term with its precise equivalent. That habit in revision becomes automatic precision in the exam.
Tip 3: The scenario is the question — answer it specifically
A generic answer in an IT exam is one that could have been written without reading the scenario. Those answers are easy to spot and easy to mark down, because the examiner can see that the student has not engaged with the specific context provided.
If the question describes a child's learning tablet, your answer about input devices needs to reference what is appropriate for a child — a touchscreen rather than a keyboard, because young children may lack the fine motor skills for typing, and the interface must be intuitive for someone with limited reading ability. If the question describes a biologist doing fieldwork in a remote location, your answer about connectivity needs to address the absence of wired infrastructure and the limitations of mobile signal in rural areas. If the question describes a vending machine, your explanation of an embedded system must reference the specific functions of that machine — detecting coin input, checking stock levels, operating the dispensing mechanism.
The test is simple: read your answer back and ask whether it could apply to a completely different scenario. If it could, it is too generic. Find one specific detail from the scenario — a named user, a named environment, a named function — and anchor at least one point in your answer to it. That is the difference between a partial mark response and a full mark one.
Tip 4: "Construct an expression" means write the formula — not the answer
This is a question type that students consistently misread, and the misreading costs them marks that were straightforwardly available.
When a question asks you to construct an expression for a file size or data transfer calculation, it is asking you to demonstrate that you know what to multiply or divide and in what order — not to produce a final numerical result. The marks are awarded for the correct structure of the expression: the right values, the right operators, arranged correctly. Arithmetic is not being tested here, and attempting it introduces the risk of calculation errors that can invalidate an otherwise correct method.
Write something like: 7 × 60 × 1024 × 1024 and stop. If the question asks for units, state them alongside. Do not reach for a calculator and do not simplify. The expression is the answer.
Tip 5: Every line in a diagram must be labelled, and every symbol must be correct
Diagram questions reward precision, and the two most common ways marks are lost are using the wrong symbol and leaving connecting lines unlabelled.
For DFDs, use only the symbols specified in Appendix 7 of the specification. Improvised or approximate symbols — a box instead of the correct process symbol, for example — will not be credited. For network diagrams, the distinction between solid lines (Ethernet/wired connections) and dotted lines (wireless connections) is a marking criterion in itself. Swapping them, or using a single line style throughout, loses those marks regardless of how accurately the devices are placed.
Every connecting line in a DFD must carry a label describing the data flowing along it. An unlabelled arrow is an incomplete diagram. Before moving on from any diagram question, trace every line and confirm it has a label.
Tip 6: The medium carries the signal — the protocol governs the communication
These two concepts operate at different levels and must not be used interchangeably.
The transmission medium is the physical path the signal travels along — copper cable, fibre-optic cable, or air. The protocol is the set of rules that governs how data is formatted, addressed, and transmitted across that medium — Ethernet, Wi-Fi, Bluetooth. They are related but distinct: Wi-Fi signals travel through air as radio waves, but Wi-Fi itself is the protocol, not the medium. Ethernet governs communication over copper or fibre cable, but "Ethernet cable" is the medium.
A reliable check: if you have named something that has physical form or substance, you have named a medium. If you have named a set of rules or a standard, you have named a protocol. Never use one where the question asks for the other.
Tip 7: SQL syntax must be exact — close is not correct
SQL mark schemes award marks for precise syntax, and small errors in keyword use or quotation mark placement are treated as wrong answers, not minor slips.
The most consistent errors are these. The equals sign = is for exact matches only. When a question requires pattern matching — finding all entries that begin with a certain letter or contain a certain string — the correct keyword is LIKE, paired with the % wildcard. Writing WHERE Name = 'S%' does not find names beginning with S; it looks for a name that is literally 'S%'. Use WHERE Name LIKE 'S%'.
On quotation marks: field names and table names do not take quotation marks. Text values being matched do. WHERE Department = Marketing is wrong; WHERE Department = 'Marketing' is correct.
For UNION queries and joins, identify the correct fields and tables before writing the query. A UNION requires both SELECT statements to return the same number of fields in the same order. A join requires a clear linking condition in the WHERE clause or using JOIN...ON syntax. Write the structure out before filling in the specific field names.
Tip 8: GPS and copyright work differently from how most people assume
Both of these concepts carry persistent misconceptions that appear regularly in exam answers and are specifically penalised because they reflect a fundamental misunderstanding of the technology or legal principle.
GPS satellites do not calculate your location. They transmit signals containing their position and a precise timestamp. Your device — phone, satnav, GPS unit — receives signals from multiple satellites simultaneously and uses the differences in signal arrival times to calculate its own coordinates through a process called trilateration. The satellite is a transmitter. The calculation happens on the device.
Copyright does not technically prevent copying. It cannot stop someone from pressing Ctrl+C. What it does is establish a legal right of ownership over original work, making unauthorised copying or distribution illegal and subject to legal consequences. The distinction matters: copyright is a legal protection, not a technical barrier. Describing it as something that "stops" copying confuses a legal mechanism with a technical one.
Tip 9: Cloud storage has real limitations — do not overstate what it can do
Exam answers about cloud storage frequently describe it in terms that are simply not accurate, and examiners penalise claims that are technically wrong regardless of how reasonable they sound.
Three specific overclaims appear most often. "Accessible anywhere" — cloud storage requires an internet connection. In areas without connectivity, access is not possible. "On any device" — a device must have the capability to connect to the internet and run the relevant application or interface. A basic peripheral like a mouse, or a device without network capability, cannot access cloud storage. "Unlimited storage" — cloud storage is finite. Providers allocate a set amount of free storage and charge for additional capacity. Describing it as unlimited is factually incorrect.
When writing about cloud storage, keep claims grounded: it is accessible from any internet-connected device with appropriate permissions, it allows remote access and file sharing, and storage capacity is determined by the user's subscription tier. Those statements are accurate and creditworthy.
Has the Edexcel IAL Information Technology (YIT11) specification changed for the 2027 examinations?
No structural changes. The 2018 specification (YIT11) remains fully intact for 2027, with the same unit codes, modular breakdown, and assessment styles across the January, May/June, and October series.
The four-unit structure stays unchanged:
Unit | Level | Mode | Focus |
WIT11 | IAS | Written exam (2h) | Hardware, software, networks, data |
WIT12 | IAS | Practical exam (3h) | Database and spreadsheet skills |
WIT13 | IA2 | Written exam (2h) | Systems methodologies, cybersecurity, management |
WIT14 | IA2 | Practical exam (3h) | Web design (HTML/CSS) and relational databases |
One adjacent development worth noting
Pearson has launched a brand-new IAL Computer Science qualification alongside the existing IT track. First teaching begins September 2026, with the first IAS assessments in May/June 2027 and the full IAL assessment from May/June 2028. This is an entirely separate qualification — it doesn't affect the IT specification — but it's worth being aware of if you're advising students on subject choices going forward.
When are the Edexcel IAL Information Technology exams held, and what are the 2027 dates?
Unlike many other IAL subjects, IT (YIT11) is only available in two series per year — January and May/June. There is no October sitting, so plan accordingly.
January 2027 (confirmed):
Unit | Date | Session | Duration |
WIT11 | Tue, 12 Jan | Afternoon | 2h |
WIT12 | Fri, 15 Jan | Morning | 3h |
WIT13 | Wed, 20 Jan | Morning | 2h |
WIT14 | Fri, 22 Jan | Morning | 3h |
May/June 2027 (provisional):
Unit | Date | Session | Duration |
WIT11 | Thu, 6 May | Morning | 2h |
WIT12 | Fri, 14 May | Morning | 3h |
WIT13 | Wed, 19 May | Morning | 2h |
WIT14 | Mon, 24 May | Morning | 3h |
Note on Units 2 and 4
These are 3-hour computer-based practical exams covering databases, spreadsheets, and HTML/CSS. Centre coordination is critical — workstations, data files, and secure environments need to be ready well ahead of the morning start times.
