What are the advanced tasks in the dMAT Battery Science subject module?
The advanced tasks give two topic sets per discipline, ten total: acid base reactions and infrared spectroscopy in chemistry, oscillations and waves in physics, combinational logic and data transformations in computer science, resistor networks and system analysis in electrical engineering, and mathematics plus the Rankine cycle in mechanical engineering.
Once you move past the five foundational basic tasks, your subject module opens into ten advanced task sets, two for every discipline. These go well beyond the basics, so this is where your own engineering background will matter most for how comfortable the questions feel.
All Ten Advanced Task Topics
| Discipline | Advanced Topic 1 | Advanced Topic 2 |
|---|---|---|
| Chemistry | Acid Base Reactions | Infrared Spectroscopy |
| Physics | Oscillations and Corrections | Waves and Solid States |
| Computer Science | Combinational Logic | Linear Transformations of High Dimensional Data Sets |
| Electrical Engineering | Series and Parallel Connections of Ohmic Resistors | System Analysis |
| Mechanical Engineering | Mathematics II | The Rankine Cycle |
How to Read This Ceiling
- You will not face all ten sets in a single sitting, since your subject module draws from the discipline relevant to your background.
- Topics like infrared spectroscopy and system analysis clearly connect to real battery work, in materials characterisation and control systems respectively.
- Every exercise in the official preparatory materials comes with a full worked solution, so use them to see exactly how deep each advanced topic actually goes.

My Advice
Once you know which discipline matches your background, treat this list as your final revision checklist and work through both advanced topics for that discipline in detail, rather than spreading thin effort across all ten. Save the free official practice exercises for these advanced sets until closer to your exam date, since they show you the true difficulty ceiling you need to be ready for.
More expert answers
Your dMAT Battery Science subject module tests two advanced computer science topics if you choose this discipline: Combinational Logic and Linear Transformations of High-Dimensional Data Sets, the latter built around Linear Discriminant Analysis (LDA). You will read a short technical passage and then answer four-option questions that check whether you can apply, not just recall, this material.
Advanced Computer Science Tasks at a Glance
| Task | Core Concept | Where It Connects to Batteries |
|---|---|---|
| Combinational Logic | Logic gates, truth tables, Boolean expressions with no memory of past states | Decision circuits inside a battery management system, such as cutoff logic for overvoltage |
| Linear Transformations of High-Dimensional Data Sets | Projecting many-variable data onto fewer dimensions, including Linear Discriminant Analysis (LDA) | Turning thousands of sensor readings per cell into a handful of health indicators |
How to Prepare Without the Official Questions
- Revise truth tables and how AND, OR, NOT and XOR gates combine into a single combinational circuit, since the exam builds new circuits from a passage rather than testing memorised diagrams.
- Refresh how LDA differs from plain dimensionality reduction: it looks for the axis that best separates known classes, not just the axis of maximum variance.
- Practice reading a short technical paragraph and quickly extracting the two or three numbers or rules you need, since the passage format rewards fast comprehension over prior memorisation.
- Remember you cannot take notes in the exam, so rehearse doing this kind of reasoning entirely in your head.

My Advice
If your undergraduate degree is in computer science or IT, spend one evening redoing the logic-gates chapter from your second-year digital electronics notes and another revisiting classification techniques from any machine learning coursework you have had. That is genuinely enough to walk into this section confident, since the dMAT checks application, not obscure recall.
