JENPAS-UG cheat sheet

JENPAS-UG (Joint Entrance for admission to Nursing, Paramedical and Allied Sciences, West Bengal) tests Physics, Chemistry, Biology, and a General Test; the General Test covers English, logical reasoning, and general awareness.

Physics numericals: v = u + at, s = ut + ½at², v² = u² + 2as apply only for uniform acceleration; for variable acceleration use calculus (v = ds/dt, a = dv/dt).

Work-energy theorem: net work W = ΔKE = ½mv² − ½mu²; power P = W/t = F·v; gravitational PE near Earth = mgh.

Ohm's law V = IR; series resistance R = R₁ + R₂ + …; parallel 1/R = 1/R₁ + 1/R₂ + …; electrical power P = VI = I²R = V²/R.

Lens/mirror formula 1/f = 1/v − 1/u (lens) and 1/f = 1/v + 1/u (mirror), with sign conventions; magnification m = v/u for mirrors, m = v/u with lens convention.

Mole concept: 1 mole = 6.022 × 10²³ particles = molar mass in grams = 22.4 L of gas at STP; molarity M = moles solute / litres solution.

pH = −log[H⁺]; strong acid fully dissociates, weak acid uses Ka; pH + pOH = 14 at 25 °C.

Biology: mitosis produces two genetically identical diploid cells; meiosis produces four haploid gametes with crossing over in prophase I.

Human blood: RBCs carry haemoglobin for O₂ transport; WBCs mediate immunity; platelets (thrombocytes) mediate clotting; AB+ is universal recipient, O− universal donor.

Vital signs normal adult ranges: temperature 36.5–37.5 °C, pulse 60–100/min, respiration 12–20/min, blood pressure ~120/80 mmHg.

Universal precautions: hand hygiene before and after patient contact; gloves for body-fluid contact; sharps disposed in puncture-proof containers without recapping.

Routes of drug administration: oral, sublingual, IV, IM, subcutaneous, topical, inhalation; IV gives fastest systemic onset, oral the slowest and most variable.

Sterilisation vs disinfection: sterilisation kills all microorganisms including spores (autoclave 121 °C, 15 psi, 15–20 min); disinfection reduces pathogens on inanimate surfaces.

Body temperature regulation: hypothalamus is the thermoregulatory centre; fever is a raised set-point, heat stroke is failure of thermoregulation.

First aid priorities follow ABC: Airway, Breathing, Circulation; CPR compression-to-ventilation ratio for adults is 30:2 at 100–120 compressions/min.

Blood groups: A has anti-B antibodies, B has anti-A, AB has none, O has both; Rh-negative mother with Rh-positive fetus risks haemolytic disease.

Infection control chain: infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host; break any link to prevent infection.

English: subject-verb agreement - singular subject takes singular verb; collective nouns take singular verbs when acting as a unit.

English: active to passive conversion moves object to subject position and changes verb to be + past participle.

Reasoning: in number series, check differences, then ratios, then alternating or squared patterns before assuming randomness.

Reasoning: syllogism conclusions are valid only if true in every possible Venn arrangement of the premises.

Blood relations: draw a family tree, marking gender and generation; 'maternal' means mother's side, 'paternal' father's side.

Direction sense: track net displacement with vectors; final distance = √(Σx² + Σy²) when movements are perpendicular.

Percentage and ratio: percentage change = (new − old)/old × 100; successive discounts of a% and b% give net (a + b − ab/100)%.

Time-speed-distance: distance = speed × time; average speed for equal distances = 2xy/(x + y), not the arithmetic mean.

General awareness: Indian Constitution came into force 26 January 1950; WHO headquarters Geneva; National Health Mission launched 2013 in India.

JENPAS-UG is a single paper of multiple-choice questions with four options and one correct answer per question.

Negative marking applies to wrong answers in JENPAS-UG; unattempted questions score zero, so guessing must be weighed against penalty.

Physics, Chemistry, and Biology carry the bulk of marks; the General Test contributes a smaller share of total marks.

Questions are set at higher-secondary (10+2) level; Physics and Chemistry follow WBCHSE/CBSE Class 11–12 syllabus, Biology follows Class 11–12 botany and zoology.

Time management rule: allocate minutes proportional to marks per section so no section is left unattempted.

Answer-sheet marking uses blue/black ballpoint pen; multiple markings on one question are treated as wrong.

Eligibility for nursing/paramedical courses requires Physics, Chemistry, and Biology at 10+2 with a minimum aggregate percentage set by the counselling authority.

Dilution formula: C₁V₁ = C₂V₂ for the same solute; use it for molarity/normality dilution problems.

Ideal gas law PV = nRT with R = 0.0821 L·atm/(mol·K) or 8.314 J/(mol·K); at STP 1 mol occupies 22.4 L.

Kinematics projectile: time of flight T = 2u sinθ/g; range R = u² sin2θ/g; maximum range at θ = 45°.

Simple interest SI = PRT/100; compound interest CI = P(1 + R/100)ⁿ − P.

Genetics: monohybrid F₂ phenotypic ratio 3:1, genotypic 1:2:1; dihybrid F₂ phenotypic ratio 9:3:3:1.

Half-life: after n half-lives, remaining amount = initial × (1/2)ⁿ; applies to radioactive decay and first-order reactions.

Work-rate problems: combined rate = 1/a + 1/b; time together = ab/(a + b).

Probability: P(A or B) = P(A) + P(B) − P(A and B); independent events P(A and B) = P(A)·P(B).
