The cleanest common entry code in the country. One genuinely shared first year, no decision until the end of it, and if you pass, the specialisation you want.
DN150 gives access to all of the traditional Bachelor of Engineering degrees at UCD. UCD describes Stage 1 as essentially common, with no critical decisions to be made. Discipline talks run in both the autumn and spring terms, so you hear from each area from people who work in it before you choose.
You choose at the end of first year, and if you pass Stage 1 you can take whichever specialisation you want. UCD states one limit: choice is subject to health and safety based capacity constraints. No specialisation is published as capped or competitive, and no first year grade threshold appears anywhere we could find. That is not the same as a guarantee that none exists, so it is worth asking directly at an open day.
It is H4 Maths, not H6. This is the DN150 requirement students most often misread, and it is the one that cannot be fixed in August. You also need H6 in a laboratory science, plus O6/H7 in Irish, English and two others. In 2025 the code went to 577 points with random selection applied at that score.
Ten core modules make up fifty of the sixty credits, so five sixths of first year is the same for everybody. All six autumn modules are fixed. The choosing happens in the spring, and it is a small amount of choosing.
UCD gives forty to fifty hours a week of total student effort for six modules rather than a lecture hour count, so treat it as a full working week. Autumn lab and tutorial slots are pre-allocated; in the spring you register for them yourself. There is mandatory health and safety training before you are let near the chemistry labs. Five of the six autumn modules end in an exam worth between fifty and seventy per cent.

In the spring you take at least one of four option modules, plus one free elective from anywhere in UCD. You can trade the elective for a second option module, or for one of eight additional options. Registration reopens in January, so a choice made in September is not final.
The four options map onto the specialisations. UCD calls them strongly recommended rather than required, and says outright that you are entitled to a place on any of them. So this is a taster with a purpose, not a gate.
| Option module | Recommended if you are leaning towards |
|---|---|
CVEN10060 | Civil Engineering, or Structural Engineering with Architecture |
CHEN10010 | Chemical and Bioprocess Engineering |
COMP10060 | Mechanical Engineering, or Electrical and Electronic Engineering |
EEEN10050 | Biomedical Engineering |
Eight further modules can be taken in place of the elective:
BSEN10010 BSEN10020 CVEN10050
DSCY10060 DSCY10180 EEEN10020
IA20130. Worth a look if you already suspect where you are heading.
Ten core modules, and between them they are a fair sample of the whole discipline. If you enjoy most of these you will enjoy engineering. If you enjoy none of them, first year has told you something useful and cheaply.
MATH10250Differentiation and integration of functions of one variable, plus a start on differential equations. Limits, the product, quotient and chain rules, implicit and logarithmic differentiation, trigonometric and hyperbolic functions, and using all of it to find maxima and minima. Every other module in the degree assumes this one.
PHYC10150Mechanics and the properties of matter, waves and light. Oscillating motion, energy transformations, the thermal behaviour of materials, wave motion, light and sound, with engineering applications used throughout. There is a lab strand of team experiments and written reports.
CHEM10030Atomic theory, ionic and covalent bonding, the periodic table, the mole and stoichiometry, then physical chemistry: states of matter, equilibrium and how fast reactions go. Four three hour labs. This is the module with the mandatory health and safety training before you are let in.
EEEN10010Four parts: circuit theory and DC circuit analysis, electromagnetics, digital electronics with Boolean algebra and logic circuits, and signals, meaning frequency spectra, analogue signals and amplifiers. In the labs you design and build simple circuits yourself.
CHEN10040Computers as a tool for solving engineering problems, taught as a systematic way of breaking a problem down. You learn Excel and MATLAB properly and apply them to real engineering case studies. Not a computer science module, and none the worse for that.
CVEN10040The one nobody expects. Hands-on design work developing observation, problem solving and lateral thinking. You sketch, prototype and build models, work in design teams, and present your ideas out loud and on paper. Students who assume engineering is all equations are often surprised by this module, in both directions.
MATH10260Complex numbers in polar form, Euler's formula, complex roots of polynomials, then systems of linear equations, matrices and determinants, eigenvalues and eigenvectors, and diagonalisation. Also vectors and three dimensional geometry: dot and cross products, lines and planes in space.
MEEN10030Statics and kinematics, using Newton's laws on solids and fluids. Team lab work on the resultant of static forces and equilibrium, friction on an inclined plane, compression and tension in trusses, and motion in a straight line. The truss experiment is the moment civil engineering starts to make sense to a lot of people.
MEEN10050Thermodynamics and heat transfer: how energy is stored and moved as heat and work. Applied to power station heat engines, internal combustion engines, refrigeration and heat pumps, pumps and water turbines, and heat loss through the walls and windows of a building. The most immediately recognisable module of the ten.
PHYC10160Electricity, magnetism, quantum and nuclear physics, in four themes of three weeks each. The electricity strand covers charge and forces, fields, flux and Gauss's law, potential, dipoles, capacitance, dielectrics, current, resistance and resistivity.
You take at least one. They are the closest thing to a trial run of a specialisation, and UCD says outright you are entitled to a place on any of them.
CVEN10060What makes buildings and structures stand up. Engineering and architecture students work together in groups on it, which is the point, and it is the natural taster for Civil, or for Structural Engineering with Architecture.
COMP10060A proper structured introduction to programming, in C, the language underneath Windows, Linux, macOS and the embedded chips in ordinary objects. Recommended for Mechanical and for Electrical and Electronic, and honestly useful whichever way you go.
CHEN10010How chemical and biochemical processes are analysed. The taster for Chemical and Bioprocess Engineering, which is the branch aimed at the pharmaceutical plants that are the biggest employer of engineers in the country.
EEEN10050Physiology, biomechanics, medical devices, tissue engineering, biomedical sensors, electrophysiology and clinical engineering. The taster for Biomedical, and a good way to find out early whether you want the biology alongside the engineering.
If you are torn between two disciplines, this is the lever. Take the option for one and spend your elective on the option for the other. Two tasters, no cost, and registration reopens in January if you change your mind in the meantime.
Descriptions above are shortened and rewritten in plain English from UCD's official module descriptors. The official wording, learning outcomes and assessment breakdown are worth reading before you register.
Since the specialisation is free choice on the far side of Stage 1, first year is not about competing. It is about passing. UCD is blunt: you must pass every module.
Degree honours bands: above 3.68 for a First, 3.08 to 3.67 for a 2.1, 2.48 to 3.07 for a 2.2, and 2.00 to 2.47 for a pass. D is the minimum pass at 2.0.
Engineering is the most interest-uniform of the common entry codes. Five of the six come out RIA, realistic then investigative then artistic, and Biomedical leads on the investigative instead. If you like building things and working out why they behave as they do, all six will suit you and the choice is genuinely about the field rather than the work.
Roads, bridges, water, flood defence and the whole housing and infrastructure programme. Consistently the most employable of the six in Ireland right now, and the one with the clearest route to chartered status and to working anywhere.
The broadest of the six. Manufacturing, energy, HVAC and building services, automotive, aerospace, and the medical device cluster in Galway and the mid west. Hardest to pin to one industry, which is the point of it.
Power generation and the grid, renewables, semiconductors, embedded systems and control. The energy transition and the data centre build have both pushed demand here well past supply.
Pharmaceutical and biopharma manufacturing, food processing, and increasingly sustainability and process improvement roles. Aims squarely at the largest manufacturing sector in the country.
Medical device design and manufacture, regulatory and quality roles, clinical engineering in hospitals, and prosthetics and rehabilitation technology. Note the interest profile leads on investigative rather than realistic, which matches the reality: more analysis and regulation, less site work.
The structural side of buildings, worked alongside architects rather than after them. Suits somebody who wanted architecture but also wants the engineering, and it keeps both doors open longer than either single degree does.
UCD pages disagree with each other about how many there are. The main course page lists six. myUCD also lists Sustainable Systems Engineering, and Biosystems and Food Engineering runs its own Stage 1 discipline talk. Check the current list before ruling anything in or out.
Ask at the open day: has any specialisation ever been oversubscribed, what happens if it is, and which of the four spring options would you recommend for somebody still undecided between two disciplines.
