DELTA Module One common mistakes
DELTA Module One · Understand the traps and how to avoid them.
Writing a description of a classroom activity instead of an analysis of the language or methodology point the task asks about - e.g. narrating 'first I would drill, then pairs practise, then feedback' when the question asks why a particular tense is difficult or what a term means.
Candidates are experienced teachers and default to lesson-planning mode under time pressure; the exam rewards analytical, terminology-anchored answers, and the habit of practical narration is deeply ingrained from daily work.
What to do instead
Before writing, underline the exact command word (analyse, explain, identify, describe-and-justify) and the number of points required. Draft each point as a claim plus a reason plus a linguistic or methodological example, and delete any sentence that describes a sequence of classroom events rather than explaining a concept.
Producing vague, non-technical answers where a named concept is required - e.g. writing 'it shows the action is happening now' instead of naming present continuous and contrasting it with present simple for habits and states.
Candidates know the grammar intuitively but have not consolidated the metalanguage, or fear using a term wrongly, so they retreat to safe everyday phrasing that scores no marks for terminology.
What to do instead
Build a personal glossary of the syllabus terms (tense/aspect, modality, cohesion, phoneme, stress-timed, lexis, register, function, skills sub-skills) and practise writing one-sentence definitions with an example for each. In answers, always name the term and immediately illustrate it with a short example sentence or phonemic transcription.
Giving a single generic reason when the task asks for several distinct points - e.g. listing only 'it is different from their L1' as the reason a feature is hard, when three or four separate reasons are needed.
Candidates misjudge the mark allocation and stop at the first plausible idea; they also confuse 'one good reason' with 'all the required reasons' and run out of thinking time.
What to do instead
Count the marks or the number of points demanded and plan that many numbered bullets before writing. Use a mental checklist of reason types - L1 transfer, complexity of form, meaning/use subtlety, pronunciation/spelling irregularity, frequency in input, learner age/level - and pick distinct ones rather than restating the same idea in different words.
Confusing levels of language description - mixing phonology, lexis and grammar in one point, or labelling a word-formation issue as a pronunciation issue, so the analysis is technically wrong even if the observation is true.
Real classroom problems are mixed, and candidates describe the symptom ('they say it wrong') without diagnosing which system is at fault; the exam separates grammar, lexis, phonology and discourse.
What to do instead
For every problem, first classify it: is it form (grammar/morphology), meaning (lexis/semantics), sound (phonology), or use (function/discourse/register)? Then write the diagnosis in that system's terms. Practise by taking a learner error and stating which system it belongs to before proposing a fix.
Answering the phonology questions with impressionistic spelling-based descriptions - e.g. 'the stress is on the second part' or 'it sounds soft' - instead of using phonemic script, stress marks and named features such as weak forms, elision, assimilation or linking.
Many candidates are less confident with phonology than grammar and avoid symbols; they also under-prepare the phonemic chart and suprasegmental terminology because it feels peripheral.
What to do instead
Learn to transcribe the target items you are likely to meet (common suffixes, word stress in two-syllable nouns versus verbs, schwa in unstressed syllables) and memorise a short list of connected-speech terms with one example each. In answers, mark primary stress with a raised vertical line and use IPA for the segment in question.
Treating lexis questions as grammar questions - describing collocation, register, connotation or word formation as if they were tense or sentence-pattern problems, or ignoring the difference between meaning and use.
Candidates are trained to spot grammar errors and overlook lexical ones; the vocabulary syllabus (collocation, chunks, synonymy, antonymy, style, word families) is less familiar and easily collapsed into 'they don't know the word'.
What to do instead
Revise the lexical relations explicitly and practise labelling a vocabulary item by its collocates, register, connotation and morphological family. When a task involves a lexical item, state its meaning, its typical collocates or context, and any connotation, rather than describing a sentence structure.
Ignoring the learner and context information given in the prompt - writing a general answer about 'students' when the task specifies level, L1, age or purpose, and so missing the points that depend on that context.
Candidates skim the rubric to save time and answer from general experience; they also assume a generic answer will cover the marks.
What to do instead
Read the prompt twice and highlight every contextual detail (level, age, L1, exam goal, class size). Then make at least one point that explicitly uses each highlighted detail - e.g. 'at B1 the present perfect is newly introduced, so confusion with past simple is expected' - so the answer is visibly tailored.
Misreading the task type - writing an essay or a lesson plan where a set of short analytical points is required, or vice versa - and so losing marks for relevance and for not covering the required number of items.
Candidates transfer habits from other assignments and from training courses where extended prose is rewarded; the exam rewards concise, itemised, on-task answers under strict timing.
What to do instead
Practise recognising the task formats and their expected answer shapes (identify-and-explain, analyse-and-justify, compare, evaluate). Before writing, sketch the number of points and a one-line plan for each; keep to bulleted or clearly paragraphed points and check at the end that every required item has an answer.
Running out of time because too long is spent on the first task or on drafting and redrafting, leaving later sections unanswered or rushed.
Candidates underestimate how much writing the paper demands and over-invest in the opening questions; perfectionism and unfamiliarity with the timing of each section compound this.
What to do instead
Do timed practice under exam conditions, allocate minutes per section in proportion to marks, and enforce a hard stop per question. Answer every question even briefly rather than leaving blanks, and reserve the final minutes for checking that all parts are addressed.
Using terminology imprecisely or inconsistently - swapping 'approach', 'method' and 'technique', or 'accuracy' and 'fluency', or calling any pair work 'communicative' - so the analysis contradicts itself.
These terms overlap in everyday staffroom talk, and candidates have not pinned down the distinctions the syllabus expects; they also use fashionable labels as filler.
What to do instead
Write one-line definitions with a concrete example for the commonly confused sets (approach/method/technique; accuracy/fluency; test/assessment; error/mistake; acquisition/learning; skimming/scanning/intensive/extensive reading) and check every use against them. If a term is not needed, cut it rather than using it loosely.
