PSEB SS Biology study plan

Skim the full Biology syllabus and mark every unit as strong, weak, or unknown to build a personal priority list.

Define and correctly use the core vocabulary of reproduction in flowering plants and human reproduction, including microsporogenesis, double fertilization, and the menstrual cycle phases.

Draw and label the male and female reproductive systems plus the structure of an ovule and embryo sac from memory, then check against your textbook.

Solve 20 short-answer questions on gametogenesis and fertilization, writing each answer in exam-style length.

Explain reproductive health topics: contraception methods, sexually transmitted infections, infertility treatments, and amniocentesis, in your own words.

Compare Mendelian inheritance patterns by working through monohybrid, dihybrid, and test-cross problems until you can predict ratios without notes.

Interpret pedigree charts and solve problems on incomplete dominance, codominance, and multiple alleles including ABO blood groups.

Describe the chromosomal basis of inheritance, including linkage, recombination, and sex-linked inheritance in humans.

Outline the molecular basis of inheritance: DNA structure, packaging, replication, transcription, and translation, and draw each process as a simple flow diagram.

Summarise the experiments that established DNA as genetic material and explain the genetic code, mutations, and the lac operon concept.

Explain the principles of inheritance of one and two genes and apply them to solve linkage and recombination frequency questions.

Define the stages of the cell cycle and describe meiosis with emphasis on the events that create genetic variation.

Describe the theory of evolution, evidence from palaeontology, comparative anatomy, and molecular data, and explain natural selection with worked examples.

Explain human evolution and the Hardy-Weinberg principle, and solve allele-frequency problems using it.

Consolidate weeks 1 to 3 by re-attempting every previously wrong question without notes.

Write timed answers to 10 long-answer questions drawn from reproduction, genetics, and evolution.

Explain human health and disease: pathogens, immunity, vaccines, allergy, autoimmunity, and the HIV/AIDS progression pathway.

Describe the principles of biotechnology, including recombinant DNA technology, restriction enzymes, vectors, and the polymerase chain reaction.

List and explain applications of biotechnology in medicine, agriculture, and industry, with named examples such as insulin and Bt cotton.

Distinguish innate from acquired immunity and describe the structure and function of antibodies.

Explain ecosystems: energy flow, trophic levels, ecological pyramids, nutrient cycling, and primary productivity, and calculate ecological efficiency from given data.

Describe biodiversity and conservation, including patterns of biodiversity, causes of loss, and in-situ and ex-situ conservation strategies.

Summarise environmental issues such as pollution, greenhouse effect, ozone depletion, and deforestation with their causes and remedies.

Apply population interaction concepts (mutualism, parasitism, competition, predation) to given scenarios.

Revise the entire syllabus using active recall, writing key definitions and processes from memory before checking notes.

Solve at least 60 objective-type questions across all units and log every recurring error by topic.

Practise diagram-based and data-interpretation questions under time pressure.

Re-teach two weak topics aloud or in writing as if explaining to a classmate, to expose gaps.

Target the five weakest topics from week 7 with focused re-study and 10 new practice questions each.

Rehearse exam strategy: question selection, time allocation per section, and presentation of diagrams and numericals.

Complete two short timed revision cycles covering all units at high speed.

Review the error logs from weeks 1 to 7 and confirm each mistake is now understood.
