UAE TLS Biology Test study plan

Map the four macromolecule classes to their monomers, bonds and cellular roles, then draw a one-page synthesis-and-hydrolysis reference sheet from memory

Trace glycolysis, the Krebs cycle and oxidative phosphorylation step-by-step, labelling ATP and electron-carrier yields at each stage without notes

Compare passive diffusion, facilitated diffusion, active transport and osmosis by predicting the direction and rate of net movement in three worked scenarios

Solve 30 calculation items on enzyme kinetics, water potential and molarity, and record every error with its correction in a log

Solve monohybrid, dihybrid and sex-linked crosses using Punnett squares and state the expected phenotypic ratios in lowest terms

Distinguish mitosis from meiosis by sketching each stage and annotating chromosome number, crossing over and independent assortment

Interpret pedigree diagrams to assign genotypes and justify dominant, recessive, autosomal and X-linked inheritance patterns

Explain how DNA replication errors and mutagens produce point mutations, frameshifts and chromosomal aberrations, and predict their protein-level effects

Work through 25 genetics problems under a 40-minute timer and classify each mistake as conceptual, computational or misread

Describe the structure-to-function link for each of the eleven human body systems and state one measurable homeostatic variable each system regulates

Trace the pathway of blood through the heart and both circuits, labelling valves, vessels and the origin of the electrical impulse

Explain nephron function in filtration, reabsorption and secretion, and predict the effect of ADH and aldosterone on urine concentration

Compare the roles of the nervous and endocrine systems in negative feedback, using blood glucose and thermoregulation as worked examples

Answer 40 mixed physiology items with labelled-diagram recall and log any system where accuracy falls below 70%

Compare the mechanisms of natural selection, genetic drift, gene flow and mutation, and explain how each can shift allele frequencies in a population

Construct a cladogram from a supplied character matrix and justify each branching decision with shared derived traits

Classify representative organisms across the major kingdoms and domains, stating the defining features used for each placement

Analyse energy flow and trophic efficiency in a food web, calculating the 10% transfer rule and predicting the effect of removing a keystone species

Interpret population growth curves and carrying capacity data, and evaluate two human impacts on UAE terrestrial or marine ecosystems using evidence

Relate leaf, root and stem anatomy to transport, gas exchange and support, and explain transpiration pull and the pressure-flow hypothesis in the phloem

Compare C3, C4 and CAM photosynthesis and predict which strategy suits a hot, arid habitat and why

Outline the steps of recombinant DNA technology, from restriction digestion and ligation through transformation, selection and screening

Explain PCR, gel electrophoresis and CRISPR-Cas9 by stating the principle, the required components and one limitation of each

Evaluate one ethical or biosafety issue in gene editing and defend a position with two pieces of evidence

Identify independent, dependent and controlled variables in ten experimental scenarios and write a testable hypothesis with a predicted direction for each

Select appropriate statistical treatments (mean, range, chi-square, correlation) for given datasets and interpret p-values correctly

Apply laboratory safety rules to five hazard scenarios, including chemical handling, glassware, biological spill and waste disposal

Design a 45-minute inquiry-based lesson for a stated curriculum outcome, including a phenomenon, a student investigation and an assessment check

Convert three practical activities into safely resourced, low-cost versions suitable for a school laboratory with limited equipment

Re-solve every item from the week 1 and week 2 error logs unaided and confirm each correction in writing

Complete two 30-question timed sets on cell biology and genetics at exam pace, then analyse accuracy by subtopic

Build a spaced-repetition deck of 60 high-yield facts drawn from across all nine domains, weighted toward Domains 1, 2 and 3

Explain aloud, in under three minutes each, five commonly confused pairs (e.g., mitosis versus meiosis, competitive versus non-competitive inhibition) without notes

Complete two full-length timed mock exams under exam conditions and record section-by-section accuracy against the domain weightings

Re-teach the three weakest subtopics identified in the mocks using a blank-page recall method, then re-test with 20 fresh items

Verify that Domain 5, 6 and 7 content is retrievable by answering 10 rapid-fire items per domain and flagging anything below 70%

Write a one-page exam-day strategy covering time allocation per domain weighting, question-ordering rules and a triage rule for flagged items
