AP SSC General Science (BSEAP) study guide
AP SSC General Science (BSEAP) · Work through your exam, one topic at a time.
The AP SSC General Science examination is the science component of the Secondary School Certificate (Class X) public examination conducted by the Board of Secondary Education, Andhra Pradesh (BSEAP). It is taken by students completing Class X in Andhra Pradesh schools and serves as the school-leaving science credential used for higher secondary admission, polytechnic and ITI entry, and as a basic eligibility record for many state-level recruitments. The AP SSC General Science (BSEAP) study guide has 16 sections and about 5,552 words.
01Reflection of Light at Curved Surfaces
Curved mirrors are portions of hollow spheres. The AP paper asks you to draw ray diagrams, apply the mirror formula with correct signs, and explain the uses of concave and convex mirrors.
396 words, about 2 min02Chemical Reactions and Equations
This domain tests balancing equations with state symbols and identifying the reaction type; every equation you write must be balanced atom by atom. Combination: A + B → AB, e.g.
311 words, about 2 min03Acids, Bases and Salts
Questions here test indicators, the pH scale, preparation and uses of common salts, and equations for acid–base reactions. Acids give H+ (or H3O+) ions in water; bases give OH−; a base soluble in water is an alkali.
348 words, about 2 min04Refraction of Light at Plane Surfaces
Light bends at the boundary between two media because its speed changes; this is refraction. The paper tests Snell's law, refractive index, total internal reflection and everyday effects such as a pencil looking bent in water.
363 words, about 2 min05Human Eye and Colourful World
The paper tests the structure and accommodation of the eye, correction of defects with lens power, dispersion through a prism, and scattering of light in the atmosphere. The cornea and the crystalline lens focus light onto the retina, where rods detect dim light and cones detect colour.
385 words, about 2 min06Structure of Atom
This domain tests the discovery of subatomic particles, the Rutherford and Bohr models, atomic number and mass number, electronic configuration, valency and isotopes. Electrons were identified in cathode rays by J.J.
340 words, about 2 min07Classification of Elements – Periodic Table
The paper tests the historical development of the periodic table, its periods and groups, and the trends in atomic radius, metallic character, ionisation energy and valency. Mendeleev arranged elements by atomic mass and left gaps for undiscovered elements, but the argon–potassium and cobalt–nickel pairs broke his order.
356 words, about 2 min08Chemical Bonding
The paper tests why atoms combine, how ionic and covalent bonds form, how to draw electron-dot structures, and how bonding explains melting points and electrical conductivity. Atoms react to reach a stable noble-gas configuration, usually eight electrons in the outermost shell.
342 words, about 2 min09Electric Current and Its Effects / Electromagnetism
The paper combines Ohm's law, series and parallel circuits, the heating effect, electric power, and the magnetic effects of current including the motor and generator. Current I = Q/t, measured in amperes.
386 words, about 2 min10Principles of Metallurgy
This domain tests the extraction of metals from ores: concentration, roasting, calcination, reduction, flux and slag, and refining, all decided by the activity series. A mineral is a naturally occurring compound of a metal; an ore is a mineral from which the metal can be extracted profitably.
347 words, about 2 min11Carbon and Its Compounds
The paper tests tetravalency and catenation, allotropes, saturated and unsaturated hydrocarbons, functional groups, homologous series, isomerism, and the chemistry of ethanol and ethanoic acid. Carbon is tetravalent and shows catenation, forming long chains, branches and rings.
324 words, about 2 min12Heredity and Evolution
This domain tests Mendel's laws, monohybrid and dihybrid ratios, sex determination, sources of variation, natural selection and the evidence for evolution. Mendel crossed tall and short pea plants.
362 words, about 2 min13Coordination in Life Processes
This domain tests how digestion, respiration, transport and excretion are coordinated, and how nerves and hormones control the body through reflex arcs and feedback loops. Digestion is enzymatic and pH-dependent.
329 words, about 2 min14Reproduction
This domain covers asexual and sexual reproduction, flower structure and double fertilisation, human reproductive systems, and reproductive health. One parent, no gametes: binary fission (Amoeba), budding (Hydra, yeast), fragmentation (Spirogyra), regeneration (Planaria), spore formation (Rhizopus), and vegetative propagation (sugarcane, potato, Bryophyllum leaf buds).
302 words, about 2 min15Natural Resources
The paper tests the composition of air, the water and soil cycles, forests and fossil fuels, biogeochemical cycles, the ozone layer and conservation practices. Air is about 78% nitrogen, 21% oxygen and 0.03–0.04% carbon dioxide, with inert gases and water vapour.
326 words, about 2 min16Our Environment
This domain tests ecosystem structure, food chains and webs, energy flow and the 10% law, biomagnification, ozone depletion, and waste management. An ecosystem has biotic components (producers, consumers, decomposers) and abiotic factors such as light, temperature, water and soil.
