Assam ASSEB HSLC General Science study guide
Assam ASSEB HSLC General Science · Work through your exam, one topic at a time.
The Assam ASSEB HSLC General Science examination is the Class 10 science assessment conducted by the Assam State School Education Board (ASSEB) for students completing secondary education in Assam. It is a high-stakes board examination that serves as a qualification for further academic study and is often required for admission to higher secondary courses and for various vocational and competitive pathways. The Assam ASSEB HSLC General Science study guide has 12 sections and about 4,061 words.
01Matter and Its Nature
Matter and Its Nature opens the ASSEB HSLC General Science paper, and it tests whether you can classify a substance and choose a separation method from evidence rather than from memory. Expect one-mark classification items, method-selection items, and a short-answer item on the interconversion of states.
399 words, about 2 min02Atomic Structure and Chemical Bonding
Atomic structure and bonding is where the paper stops asking only for recall and starts asking you to write: electronic configurations, ion charges, formulae and balanced equations. An atom has protons (positive, in the nucleus), neutrons (neutral, in the nucleus) and electrons (negative, in shells).
331 words, about 2 min03Acids, Bases and Salts
Acids, bases and salts carries easy theory marks plus one reliable practical-style question: identifying a substance from its behaviour with an indicator, or writing a neutralisation equation. Acids taste sour, turn blue litmus red, release H⁺ ions in water, react with metals to give hydrogen, with carbonates and hydrogencarbonates to give carbon dioxide, and with bases to give salt and water.
368 words, about 2 min04Metals and Non-metals
Metals and non-metals tests the reactivity series more than it tests memorised properties, and extraction and corrosion questions come straight out of that ranking. Metals are lustrous, malleable, ductile, sonorous and conduct heat and electricity; the exception is mercury, a liquid.
323 words, about 2 min05Carbon Compounds and Fuels
Carbon compounds and fuels covers hydrocarbons, functional groups, soaps and combustion. Questions are formula-based and usually ask you to distinguish two compounds by a test.
341 words, about 2 min06Cell and Tissues
Cell and tissues asks for structure–function links: which organelle does what, and which tissue performs which job. The plasma membrane is selectively permeable; the cell wall (plants, fungi, bacteria) is made of cellulose and gives rigidity.
280 words, about 1 min07Life Processes
Life processes covers nutrition, respiration, transport and excretion - mostly process-pathway and labelled-diagram questions. Photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂, in chloroplasts, using chlorophyll and sunlight; stomata admit CO₂ and release O₂.
314 words, about 2 min08Control and Coordination, Reproduction and Heredity
This domain joins two chapters: control and coordination through nerves and hormones, and reproduction with basic genetics. The neuron has a cell body, dendrites and an axon; a synapse passes the signal chemically.
321 words, about 2 min09Health, Disease and Environment
Health, disease and environment mixes biology with environmental issues - disease transmission, immunity, ecosystems and conservation. Infectious diseases spread through pathogens.
321 words, about 2 min10Motion, Force and Laws of Motion
Motion, force and laws of motion supplies the numerical part of the physics section: speed, acceleration, graphs and Newton's laws. Distance is a scalar; displacement is a vector and is always less than or equal to the distance.
338 words, about 2 min11Gravitation, Work, Energy and Power
Gravitation, work, energy and power links forces to energy accounting, so most questions are one-step calculations with a single trick hidden in the wording. Universal law: F = Gm₁m₂/r², with G = 6.67 × 10⁻¹¹ N m²/kg².
352 words, about 2 min12Light, Sound and Electricity
Light, sound and electricity is the largest physics block: mirror and lens calculations, sound, and Ohm's law circuits, often with a heating or magnetic effect item. Angle of incidence = angle of reflection.
