BCS Written Zoology study plan

BCS Written Zoology · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Cell Biology, Genetics and Molecular Biology & Animal Diversity, Systematics and Taxonomy

  • Draw and label the cell cycle and organelle functions from memory, then check against a textbook and correct errors

  • Solve 20 genetics problems on Mendelian ratios, linkage and probability, writing out each cross

  • Build a one-page comparison table of the 10 major invertebrate phyla using body plan, symmetry, coelom and larval type

  • Define 40 taxonomy terms (holotype, synonymy, paraphyly, priority) in a personal glossary with examples

Your checkpoint

A corrected hand-drawn cell/organelle map plus a completed 20-problem genetics set with all working shown

Week 2

Cell Biology, Genetics and Molecular Biology & Animal Diversity, Systematics and Taxonomy

  • Explain DNA replication, transcription and translation step by step to a study partner or recorder without notes

  • Perform 15 molecular biology calculations covering GC content, codon degeneracy and PCR product size

  • Construct a dichotomous key that separates 8 local animal specimens or pictured taxa

  • Summarise the rules of zoological nomenclature and apply them to correct three deliberately flawed species names

Your checkpoint

A 10-minute recorded or written walkthrough of the central dogma, plus a working dichotomous key with answer check

Week 3

Animal Physiology and Endocrinology & Developmental Biology and Embryology

  • Diagram the nephron, alveolus and cardiac cycle and annotate the regulatory hormones at each site

  • Compare endocrine axes (hypothalamus-pituitary-thyroid, adrenal, gonadal) in a table showing feedback type and target

  • Trace cleavage through gastrulation and neurulation for frog, chick and mammal, listing one difference per stage

  • Answer 12 short physiology questions under timed conditions and mark them against model answers

Your checkpoint

A labelled comparative embryology chart for three vertebrate models plus a scored timed physiology answer set

Week 4

Animal Physiology and Endocrinology & Developmental Biology and Embryology

  • Explain osmoregulation in freshwater, marine and diadromous fishes with direction of water and ion movement

  • Describe metamorphosis and its hormonal control in amphibians and insects

  • Identify the extraembryonic membranes and their functions in amniotes

  • Write 300 words on how a named teratogen disrupts a specific developmental stage, citing the mechanism

Your checkpoint

A 300-word mechanism essay on teratogenesis plus a completed osmoregulation flow diagram

Week 5

Ecology, Biodiversity and Conservation & Evolution and Population Genetics

  • Calculate population size estimates using mark-recapture and quadrat data, and state assumptions

  • Apply Hardy-Weinberg to five allele-frequency problems, including selection and drift scenarios

  • Compare r- and K-selection and life-history trade-offs using three named species

  • Classify 15 conservation status cases against IUCN Red List criteria categories

Your checkpoint

A problem set of 10 solved population and Hardy-Weinberg calculations with assumption notes for each

Week 6

Ecology, Biodiversity and Conservation & Evolution and Population Genetics

  • Explain speciation modes (allopatric, sympatric, polyploidy) and give one empirical example of each

  • Summarise island biogeography and metapopulation theory and apply them to a reserve-design scenario

  • Describe three biodiversity survey methods and state the bias of each

  • Write a 400-word argument on a named conservation conflict, presenting both sides and a recommendation

Your checkpoint

A 400-word evidence-based conservation recommendation for a named reserve scenario

Week 7

Fisheries, Aquaculture and Wildlife Management & Parasitology, Immunology and Public Health

  • Compare pond, cage and raceway aquaculture systems on stocking density, water quality and species suitability

  • Outline the life cycle and control measures for three parasites of public health or aquaculture importance

  • Explain innate versus adaptive immunity and the antibody response curve after first and second exposure

  • Describe wildlife census techniques (transect, point count, camera trap) and select one for a stated objective

Your checkpoint

A two-page parasite control and immunity summary table linking each parasite to a control measure and host immune response

Week 8

Applied Zoology, Biotechnology and Research Methods & Cell Biology, Genetics and Molecular Biology & Ecology, Biodiversity and Conservation

  • Design a small research project with hypothesis, controls, sampling plan and one statistical test justified

  • Explain PCR, gel electrophoresis and ELISA principles and one limitation of each

  • Review all earlier deliverables and rewrite the five weakest explanations from memory

  • Complete a full timed mock paper across all nine domains and record per-domain scores

Your checkpoint

A one-page research proposal plus a scored mock exam with a per-domain error log and revision priorities

Milestones

Week 2: Can reproduce the central dogma and a phylum comparison table from memory with no more than two factual errors each

Week 4: Scores at least 60% on self-marked timed physiology and embryology questions and can explain every missed item

Week 6: Solves all Hardy-Weinberg and mark-recapture problems correctly and states the assumptions unprompted

Week 7: Links each studied parasite to a control measure and to the relevant host immune response without notes

Week 8: Mock paper shows no domain below 50% and an error log listing at least three specific revision targets
