Aragón PAU Graphic-Plastic Expression Techniques common mistakes
Aragón PAU Graphic-Plastic Expression Techniques · Understand the traps and how to avoid them.
In the drawing section, candidates start shading or rendering details immediately, without first establishing the overall proportions and compositional structure with light construction lines.
Under exam time pressure, they jump to the most visible or satisfying part (texture, eyes, highlights) and skip the slow measurement phase; they also overestimate their ability to correct proportions later.
What to do instead
Spend the first 5–10 minutes on a light structural sketch: block the whole format, locate the main axes and large masses, check proportions with a pencil held at arm's length or with vertical/horizontal reference lines, and only then build values from general to specific. Practise 10-minute structural-only studies so the habit becomes automatic.
In watercolour and wash work, candidates paint large dark areas first, then cannot lighten them, and the paper buckles or the washes bloom uncontrollably.
They treat watercolour like opaque paint, ignoring its transparent, cumulative nature; they also skip stretching or taping the paper and work on thin paper without testing absorption.
What to do instead
Work light-to-dark and transparent-to-opaque: reserve whites with masking fluid or bare paper, build in thin glazes, and let each layer dry before the next. Stretch or tape 300 g/m² paper, test pigment behaviour on a scrap, and keep a blotter and clean water for lifting. For exams, choose a limited palette and pre-mix puddles before starting.
In graphic design and illustration tasks, candidates produce a visually attractive layout but with unreadable typography: too many typefaces, poor hierarchy, insufficient contrast, and text set too close to the trim or with no margins.
They focus on decoration and image-making and treat text as filler; they have not internalised basic typographic rules (measure, leading, alignment, hierarchy) and do not proof at actual size.
What to do instead
Apply a fixed checklist before submission: maximum two type families, clear size/weight hierarchy (title, subtitle, body), consistent alignment, generous margins, adequate leading (roughly 120–140 % of type size for body text), and contrast checked in greyscale. Print or view at 100 % scale and read the text aloud to catch spacing and legibility errors.
In printmaking questions, candidates confuse relief and intaglio processes, or describe a planographic or stencil process as if it were intaglio, and cannot match tools and materials to the correct family.
They memorise isolated names (linocut, etching, lithography, screenprint) without a mental model of where ink sits relative to the plate surface and how pressure transfers it.
What to do instead
Build a comparison table organised by the physical principle: ink in recessed grooves (intaglio: etching, drypoint, aquatint, mezzotint), ink on raised surfaces (relief: woodcut, linocut), ink on a flat chemically differentiated surface (planographic: lithography, offset), and ink forced through a stencil (screenprint, stencil). For each, note matrix material, tool, ink, press type and typical visual signature; practise identifying unlabelled process samples by their characteristic marks.
In image analysis, candidates describe what is depicted (subject matter) but do not analyse formal elements-line, shape, value, colour relationships, texture, space, composition-or connect them to meaning and context.
They lack a systematic viewing method and default to narrative description; they also fear using technical vocabulary incorrectly, so they avoid it altogether.
What to do instead
Use a fixed four-step scaffold for every analysis: (1) describe objectively, (2) analyse formal elements with precise terms (e.g. complementary contrast, directional line, atmospheric perspective, asymmetrical balance), (3) interpret how those choices produce meaning or mood, (4) contextualise historically or technically. Practise on unfamiliar works with a timer, writing one sentence per formal element before any interpretation.
In the creative process/project section, candidates present only a final piece with no evidence of planning, experimentation or documentation, and cannot justify their decisions.
They equate the exam with a finished artwork and see sketchbooks, trials and notes as wasted time; they also leave documentation to the last minutes.
What to do instead
Structure the project as a visible sequence: brief and references, thumbnail composition studies, material/colour tests, one or two failed or revised attempts with annotations, final piece, and a short evaluation. In the exam, allocate explicit time blocks for each stage and keep a running annotated sheet (date, decision, reason). Even 5–6 small annotated trials demonstrate process convincingly.
When asked to place a work in its artistic or technical context, candidates name a style or artist but give no technical explanation of how the work was made or why that technique produced that visual result.
They study art history as a list of names and dates, disconnected from materials; they do not link, for example, Impressionist broken colour to portable paint tubes and plein-air practice, or Cubism to collage and multiple viewpoints.
What to do instead
For each reference movement, prepare a three-column card: technical innovation, visual consequence, representative example. Revise by explaining the causal chain aloud in one minute (e.g. oil paint's slow drying → blending and reworking → sfumato; lithography → tonal drawing directly on stone → poster art). In answers, always connect style to a named material or process.
In painting questions, candidates misjudge drying times and layering rules-applying fast-drying acrylic over oil, or thick oil layers over lean ones-and cannot explain the consequences.
They learn recipes without the underlying chemistry (oxidation vs. water evaporation) and have not handled the media enough to observe cracking, lifting or poor adhesion.
What to do instead
Memorise the practical rules with their cause: oil dries by oxidation and must be applied fat-over-lean to avoid cracking; acrylic dries by water evaporation and can be used under oil but not over it; gouache remains water-soluble and can be re-wetted. Do small layered test boards for each medium, label them, and revise from the physical samples rather than from notes alone.
Candidates handle supports and preparation carelessly: painting on the wrong side or unprimed surface, using unsuitable paper weight for wet media, or failing to prepare a ground, then blaming the medium for poor results.
They treat the support as neutral and skip preparation steps under time pressure; they also do not know the properties of common supports (cold-pressed vs. rough watercolour paper, canvas vs. board, sized vs. unsized paper).
What to do instead
Learn a support-selection decision rule: wet media need heavy, sized paper (300 g/m² or stretched lighter paper); acrylic and oil need a primed, rigid or stretched support; dry media need a paper with enough tooth. Always test on an offcut, note the manufacturer and weight, and include surface preparation in your exam time plan rather than starting to paint immediately.
In mixed-media and colour work, candidates combine incompatible materials (e.g. oil pastel under watercolour, or solvent-based markers over water-based ink) without testing, producing muddy colour, bleeding or adhesion failure, and they use colour without a stated scheme.
They are attracted by combined effects seen in finished works but have not learned which binders and solvents are compatible; colour choices are made intuitively without a plan for harmony, temperature or value structure.
What to do instead
Before the exam, build a compatibility chart (water-based under solvent-based generally safe; solvent-based under water-based generally not; oil and water media require isolation layers such as gesso or fixative). For colour, decide a limited palette and a scheme (e.g. analogous, complementary, triadic) and establish a value plan in thumbnail before applying colour. In the exam, test any new combination on a scrap corner first.
