AP Intermediate Zoology (BIEAP) study plan

AP Intermediate Zoology (BIEAP) · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Animal Physiology and Homeostasis

  • Build a one-page equation sheet covering membrane resting and action potentials, the Nernst and Goldman equations, and the cardiac cycle phases, then state each equation aloud from memory three times across the week.

  • Draw and label the nephron, the alveolus-capillary unit, and the sarcomere from blank paper, and annotate each with the transport protein or ion channel that drives its key step.

  • Explain countercurrent multiplication in the loop of Henle and countercurrent gas exchange in fish gills in writing, naming the shared physical principle and one difference in mechanism.

  • Trace the hormonal control of blood glucose, calcium, and water balance on a single feedback-loop diagram, marking each sensor, integrating centre, and effector.

  • Solve ten numerical problems on oxygen dissociation curves, GFR, and cardiac output, showing units at every step.

Your checkpoint

A handwritten 4-page physiology summary (equation sheet, three labelled diagrams, feedback-loop map) plus a 10-question self-test scored at 70% or better.

Week 2

Animal Physiology and Homeostasis & Structural Organisation and Function in Animals

  • Compare open and closed circulatory systems, single and double circulation, and the four vertebrate heart plans in a table with at least six rows.

  • Sequence the events of nerve impulse conduction and synaptic transmission, and predict the effect of three named toxins or drugs on each step.

  • Label the digestive tract of a ruminant, a bird, and a mammal side by side, and state one structural adaptation of each region to diet.

  • Describe the sliding filament theory in your own words and link each stage to the calcium and ATP requirements that control it.

  • Answer 30 mixed multiple-choice questions on domains 2 and 3 under timed conditions and log every error by cause.

Your checkpoint

A comparative anatomy-physiology table set (circulation, digestion, muscle) and an error log with 30 questions classified by mistake type.

Week 3

Genetics and Molecular Biology

  • Work through monohybrid, dihybrid, and test-cross problems until you can derive phenotypic ratios without writing the full Punnett square.

  • Solve linkage and recombination problems by constructing chromosome maps from three-point cross data, and check map distances against interference.

  • Predict pedigree inheritance patterns (autosomal dominant and recessive, X-linked recessive, Y-linked) and justify each exclusion in one sentence.

  • Explain DNA replication, transcription, and translation in a labelled flow diagram, naming each enzyme and the direction of synthesis.

  • Describe the lac operon and one eukaryotic regulatory mechanism, and predict expression outcomes for three given mutations.

Your checkpoint

A solved problem set of 25 genetics questions (ratios, mapping, pedigrees, molecular mechanisms) with full working shown and a one-page mutation-outcome summary.

Week 4

Animal Diversity and Classification & Structural Organisation and Function in Animals

  • Construct a classification key for the major invertebrate phyla using symmetry, coelom type, segmentation, and larval form as characters.

  • Compare the excretory and respiratory organs of five invertebrate phyla in a table, and state the habitat constraint each organ imposes.

  • Identify the diagnostic features of the major vertebrate classes and place ten unnamed descriptions into the correct class with reasons.

  • Explain the significance of coelom formation, metamerism, and cephalisation as evolutionary trends, citing one example animal for each.

  • Complete a 40-question cumulative test covering domains 1, 2, and 3 and re-teach your three weakest items in writing.

Your checkpoint

A two-page classification key plus a completed 40-question cumulative test with written re-teaching notes for the three weakest items.

Week 5

Reproduction and Developmental Biology

  • Label the male and female reproductive tracts and describe gametogenesis in each, including the timing of meiotic arrest in human females.

  • Sequence the hormonal events of the menstrual cycle and match each phase to endometrial and ovarian changes on a single timeline.

  • Compare fertilisation, cleavage, gastrulation, and neurulation across one invertebrate and one vertebrate example.

  • Explain the roles of the placenta, hCG, and progesterone in maintaining pregnancy, and describe one clinical consequence of each failing.

  • Describe three assisted reproductive technologies and state the biological step each one bypasses.

Your checkpoint

A single-page developmental timeline (gametogenesis to organogenesis) with a 15-term glossary and a 10-question self-quiz scored at 80% or better.

Week 6

Evolution and Animal Behaviour & Ecology and Environmental Biology

  • Summarise the evidence for evolution from fossils, comparative anatomy, embryology, and molecular data, giving one specific example per line of evidence.

  • Explain natural selection, genetic drift, gene flow, and non-random mating, and calculate allele frequency change for one worked example of each.

  • Interpret a population growth curve and a survivorship curve, and predict the effect of a named density-dependent factor on each.

  • Describe energy flow and nutrient cycling in an ecosystem, and calculate ecological efficiency across a four-trophic-level food chain.

  • Classify ten named animal behaviours as innate or learned and as proximate or ultimate, justifying each label.

Your checkpoint

A two-page evidence-and-mechanism summary (evolution, population genetics, ecology, behaviour) plus 20 solved application questions.

Week 7

Applied Zoology, Aquaculture and Biotechnology & Ecology and Environmental Biology

  • Compare composite fish culture, pearl culture, and prawn culture by species used, pond preparation, and one major disease risk for each.

  • Explain induced breeding in fish and the role of hypophysation, and list three water-quality parameters that must be monitored in aquaculture.

  • Describe three biotechnology applications in animal science (transgenics, cloning, vaccines or diagnostics) and state one ethical or regulatory concern for each.

  • Analyse a conservation case study using in-situ and ex-situ measures, and recommend two interventions with justification.

  • Calculate stocking density, feed conversion ratio, and growth rate from given aquaculture data.

Your checkpoint

An applied zoology dossier: one aquaculture plan with calculated stocking and feed figures, one biotechnology application note, and one conservation recommendation page.

Week 8

Animal Physiology and Homeostasis & Genetics and Molecular Biology

  • Re-solve every item you previously logged as an error in domains 3 and 5, and confirm each is now correct without notes.

  • Complete two full-length timed mock papers under exam conditions and record the score, time per section, and domain-wise accuracy for each.

  • Build a one-page high-yield recall sheet for each of the eight domains from memory, then fill gaps from your notes.

  • Rehearse written answers to five likely long-answer questions, keeping each to the marks available and including a labelled diagram where relevant.

Your checkpoint

Two completed mock papers with a score comparison, a corrected error log, and eight one-page recall sheets.

Milestones

Week 2: Score at least 65% on a 30-question untimed test drawn only from domains 2 and 3, and show that every equation on the physiology sheet can be reproduced from blank paper.

Week 4: Score at least 70% on the 40-question cumulative test covering domains 1, 2, and 3, with no domain below 60%.

Week 6: Produce the developmental timeline and the evolution-ecology summary from memory outlines, and score at least 70% on a 20-question mixed test of domains 4, 6, and 7.

Week 8: Average at least 75% across the two full-length mocks with no single domain below 60%, and complete all eight recall sheets without consulting notes first.
