General Knowledge and Current Affairs (Karnataka focus)
Karnataka was formed on 1 November 1956 as Mysore State and renamed Karnataka on 1 November 1973.
The state has 31 districts; the most recent additions include Vijayanagara (2018) and Chikkaballapura was carved out in 2007.

Karnataka accounts for a large share of India's coffee production (mostly Arabica and Robusta in Kodagu, Chikkamagaluru, Hassan) and is a leading producer of coarse silk and sandalwood.
Bengaluru is known as the Silicon Valley of India; the headquarters of ISRO, DRDO labs, and major IT firms are located there.
Important current affairs: Karnataka topped the NITI Aayog SDG India Index in 2020-21; the state's Gross State Domestic Product (GSDP) is among the top five in India.
General Science
Newton's laws: F = ma (second law); every action has an equal and opposite reaction (third law); an object remains at rest or in uniform motion unless acted upon by a net force (first law).
Speed of light in vacuum c ≈ 3 × 10^8 m/s; speed of sound in air at 20°C ≈ 343 m/s.
Photosynthesis equation: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2; occurs in chloroplasts, uses chlorophyll.
Human blood groups: A, B, AB, O; O negative is the universal donor, AB positive is the universal recipient; Rh factor determines positive/negative.
pH scale: acidic < 7, neutral = 7, basic > 7; litmus paper turns red in acid and blue in base.
Ohm's law: V = IR; power P = VI = I^2R = V^2/R; unit of resistance is ohm (Ω).
The three states of matter: solid (definite shape and volume), liquid (definite volume, indefinite shape), gas (indefinite shape and volume); plasma is the fourth state.
Cell organelles: mitochondria (powerhouse, ATP production), ribosomes (protein synthesis), nucleus (contains DNA), chloroplast (photosynthesis in plants).
Mathematics / Quantitative Aptitude
Percentage: part = (percent/100) × whole; to find what percent A is of B: (A/B) × 100.
Profit/loss: Profit% = (SP − CP)/CP × 100; Loss% = (CP − SP)/CP × 100; SP = CP × (100 + Profit%)/100.
Simple interest SI = P × R × T / 100; Compound interest CI = P[(1 + R/100)^T − 1].
Average = sum of observations / number of observations; if a person's average changes by x after scoring y, use total change method.
Time and work: If A can do a job in x days and B in y days, together they take xy/(x+y) days; work rate = 1/x per day.
Speed, distance, time: Distance = Speed × Time; to convert km/h to m/s multiply by 5/18; m/s to km/h multiply by 18/5.
Ratio and proportion: If a:b = c:d then ad = bc; to divide a sum in ratio a:b:c, parts are (a/(a+b+c)) × total, etc.
Area and volume: Area of circle = πr^2; circumference = 2πr; volume of cylinder = πr^2h; volume of sphere = (4/3)πr^3; area of triangle = 1/2 × base × height.
Reasoning and Mental Ability
Number series: check differences between consecutive terms; if differences are constant, it is an arithmetic progression; if ratios are constant, geometric progression.
Coding-decoding: letter positions A=1, B=2, ..., Z=26; reverse alphabet position = 27 − position (A↔Z, B↔Y, etc.).
Blood relations: draw a family tree; use symbols: + male, − female; vertical line for parent-child, horizontal for siblings/spouse.
Direction sense: draw compass; North-up, South-down, East-right, West-left; after a right turn from North, face East; after left turn from North, face West.
Syllogism: use Venn diagrams; 'All A are B' means A is subset of B; 'Some A are B' means intersection exists; 'No A is B' means disjoint sets.
Odd one out: look for pattern in properties (prime/composite, perfect squares, multiples, alphabet position parity).
Seating arrangement: for linear arrangement, note left/right; for circular, facing centre means left is clockwise, right is anticlockwise (and vice versa when facing outward).
Calendar: odd days in a normal year = 1, leap year = 2; 100 years have 5 odd days, 200 years 3, 300 years 1, 400 years 0.
Kannada Language
Kannada script is derived from the Kadamba script (a southern Brahmi variant); earliest known Kannada inscription is the Halmidi inscription (c. 450 CE).
Kannada has 49 letters in the standard alphabet: 14 vowels (swaragalu), 34 consonants (vyanjanagalu), and 1 part-vowel (yogavahaka).

Important poets: Pampa (Adi Purana, Vikramarjuna Vijaya), Ranna (Gadayuddha), Janna (Yashodhara Charite), Harihara, Raghavanka; modern: Kuvempu (Jnanpith), D.R. Bendre, V.K. Gokak.
Kuvempu's 'Jaya Bharata Jananiya Tanujate' is the Karnataka state anthem; Kuvempu was the first Kannada writer to receive Jnanpith Award (for Sri Ramayana Darshanam).

Tenses: simple present (habitual), present continuous (ongoing), present perfect (completed with relevance to now), past perfect (completed before another past action).
Active to passive: object becomes subject; verb 'be' + past participle; by + agent (optional). Example: 'She writes a letter' → 'A letter is written by her.'
Direct to indirect speech: change pronouns, tense (backshift), and time/place words (now→then, today→that day, here→there).
