Remaining academic requirements

Conceptual English-only alignment and independent AI content checks, not official Cambridge certification or teacher approval. A qualified teacher must check marking, level, route and teaching adequacy.
Inventory limitation: all numbered theoretical subsections were located/read, but this is NOT an exhaustive leaf-outcome inventory. Individual numbered outcomes, lettered clauses, example lists and all practical bullets still need a teacher-checked leaf ledger.
All listed Paper 3 apparatus/measurement/observation requirements and actual extended Paper 5 experimental planning remain practical training gaps. A numerical calculation, supplied observation or short design discussion does not demonstrate laboratory handling, microscopy drawing, data collection, a complete safe method or practical competence. No hazardous real-laboratory instructions are supplied by the additions.
New questions are original English-only selected practice with indicative distinct marking points. Independent AI checking does not establish teacher approval, validated translations or full outcome teaching coverage. Arabic practice and bilingual academic verification are not supplied here.
Subsections with no placed existing or new question at all: . Even the other subsections have only selected question presence, not complete teaching/assessment coverage.
Board-neutral enrichment retained: trophic production-efficiency and decomposer energy/nutrient-cycle drills do not have an explicit 9700 2025-2027 teaching outcome merely because 'ecosystem' is defined. Differential cell fractionation is also not named here. These questions are not evidence of Cambridge theory coverage.
Residual theory/practical depth includes full macromolecular structures and biological tests, membrane signalling diagrams, complete mitotic/meiotic stage recognition from real images, xylem/phloem plan drawings, all respiratory intermediates and pigment/Calvin evidence, cardiac tissue/airway microscopy, full pathogen case comparisons, T-cell sequence and hybridoma production, biosensors, barley/Venus-flytrap detail, linkage/epistasis crosses, Spearman/Pearson calculations, domains/kingdoms/viral classification, assisted conservation reproduction and the remaining technology examples.
Pure noncompetitive E/ES affinity detail, alternative-splicing/chromatin depth, intestinal sodium-glucose transport, causal rescue experiments, uncouplers and prolonged NMJ depolarisation block have partial/contextual placements only. The supplied cases do not establish clinical diagnosis, treatment effectiveness, exact disease risk or universally deterministic physiological effects.
