United Nations founded 24 October 1945, headquarters New York; India was a founding member; the UN observes 24 October as United Nations Day.

Reserve Bank of India established 1 April 1935, nationalised 1 January 1949; it issues currency notes (one-rupee notes are issued by the Government of India).

Nobel laureates with Indian links: Rabindranath Tagore (Literature, 1913), C. V. Raman (Physics, 1930), Amartya Sen (Economics, 1998), Kailash Satyarthi (Peace, 2014).

The Constitution was adopted by the Constituent Assembly on 26 November 1949 and came into force on 26 January 1950; Dr B. R. Ambedkar chaired the Drafting Committee.

Fundamental Rights occupy Part III (Articles 12-35); the Right to Constitutional Remedies (Article 32) was called the 'heart and soul' of the Constitution by Ambedkar.

Directive Principles of State Policy are in Part IV (Articles 36-51) and are non-justiciable; Fundamental Duties are in Part IVA (Article 51A, added by the 42nd Amendment, 1976).

Parliament consists of the President, Rajya Sabha and Lok Sabha; the Rajya Sabha has a maximum of 250 members and the Lok Sabha a maximum of 552.

The President is elected by an electoral college using a single transferable vote by proportional representation; the impeachment procedure is in Article 61.

Emergency provisions: national emergency (Article 352), President's rule/state emergency (Article 356), financial emergency (Article 360).

The Supreme Court's power of judicial review flows from Articles 13, 32 and 226 (High Courts); Article 368 governs amendment of the Constitution.

Panchayati Raj was constitutionalised by the 73rd Amendment (1992) and urban local bodies by the 74th Amendment; the 61st Amendment lowered the voting age to 18.

Coding-decoding: check for a constant letter shift (e.g. +1, -2), reversal, or letter-to-number mapping (A=1 ... Z=26) before assuming a complex rule.

Blood relations: draw a family tree using symbols; vertical lines for generations and horizontal lines for siblings/marriage, and never assume gender from a name.

Direction sense: fix north upwards; a right turn after facing north gives east, and a left turn after facing east gives north; use Pythagoras for shortest distance.

Series: for letter series check the position gap between consecutive letters; for number series test differences, ratios, squares/cubes, or alternating patterns.

Syllogism: 'All A are B' does not imply 'All B are A'; a conclusion is valid only if true in every possible diagram consistent with the statements.

Seating arrangement: for a circle, 'facing centre' means left is anticlockwise and right is clockwise; 'facing outward' reverses both.

Clocks: the minute hand gains 5.5 degrees per minute on the hour hand; hands coincide every 65 5/11 minutes.

Calendar: a normal year shifts the day by 1 and a leap year by 2; 100 years shift by 5 days and 400 years by 0 days.

Speed, time, distance: distance = speed x time; to convert km/h to m/s multiply by 5/18, and m/s to km/h multiply by 18/5.

Average = sum of observations / number of observations; if each value is increased by k, the average increases by k.

Percentage change = (new - old)/old x 100; successive changes of a% and b% give a net change of a + b + ab/100 percent.

Simple interest = P x R x T / 100; compound interest = P(1 + R/100)^T - P, compounded annually.

Profit and loss: profit% = profit/CP x 100, always computed on cost price unless stated otherwise; selling price = CP x (100 + profit%)/100.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; work done is the reciprocal of time.

Train crossing problems: time = (length of train + length of platform)/speed; for a pole or a standing person, length of platform is zero.

Ratio and mixture: in a mixture of milk and water in ratio a:b, the fraction of milk is a/(a+b); alligation gives the ratio of quantities mixed as (mean price - cheaper)/(dearer - mean price).

Subject-verb agreement: a singular subject takes a singular verb; with 'either...or' and 'neither...nor' the verb agrees with the nearer subject.

Articles: 'a' before consonant sounds, 'an' before vowel sounds (an hour, a university); 'the' is used for unique things and superlatives.

Tenses: use present perfect (has/have + past participle) for past actions with present relevance; 'since' takes a point of time, 'for' takes a duration.

Prepositions of time: 'in' for months/years, 'on' for days/dates, 'at' for clock times; 'between' takes two items and 'among' more than two.

Active to passive: object becomes subject, verb becomes be + past participle, and the doer is introduced by 'by'; tense of the original is preserved.

Direct to indirect speech: present tenses shift to past, 'this' becomes 'that', 'now' becomes 'then', and 'today' becomes 'that day'.

Commonly confused pairs: affect (verb) / effect (noun), principal (head, main) / principle (rule), stationary (not moving) / stationery (writing material).

Synonyms and antonyms are best answered by substituting the word into the sentence; idioms carry a fixed figurative meaning, e.g. 'to burn the midnight oil' means to study or work late.

বাংলা বর্ণমালায় স্বরবর্ণ ১১টি ও ব্যঞ্জনবর্ণ ৩৯টি; মোট ৫০টি বর্ণ, সঙ্গে অ আ-কার ইত্যাদি কারচিহ্ন ব্যবহৃত হয়।

স্বরবর্ণের দুই ভাগ: হ্রস্বস্বর (অ, ই, উ, ঋ) ও দীর্ঘস্বর (আ, ঈ, ঊ, ৠ); ব্যঞ্জনবর্ণে স্পর্শ, অন্তঃস্থ ও ঊষ্ম বর্ণ রয়েছে।

সন্ধি প্রধানত তিন প্রকার: স্বরসন্ধি (বিদ্যা + আলয় = বিদ্যালয়), ব্যঞ্জনসন্ধি (উৎ + হার = উত্থার/উদ্ধার), বিসর্গসন্ধি (নিঃ + রব = নীরব)।

সমাসের প্রধান ভেদ: দ্বন্দ্ব, কর্মধারয়, তৎপুরুষ, বহুব্রীহি, দ্বিগু এবং অব্যয়ীভাব; 'রাজপুত্র' কর্মধারয় নয়, তৎপুরুষ সমাসের উদাহরণ।

কারক ও বিভক্তি: কর্তৃকারকে শূন্য বিভক্তি, কর্মকারকে দ্বিতীয়া, করণকারকে তৃতীয়া, সম্প্রদানকারকে চতুর্থী, অপাদানকারকে পঞ্চমী, অধিকরণকারকে সপ্তমী।

সমার্থক শব্দ মনে রাখার উদাহরণ: জল = বারি, পানি, অম্বু; সূর্য = রবি, ভানু, দিবাকর; পদ্ম = কমল, নলিনী, পঙ্কজ।

বিপরীত শব্দ: আলো-অন্ধকার, জ্ঞান-অজ্ঞান, সৎ-অসৎ, সৃষ্টি-প্রলয়; বিদেশি শব্দের বানানে বাংলা প্রত্যয় যোগের নিয়ম খেয়াল রাখতে হয়।

বাগধারা অর্থসহ: অগস্ত্য যাত্রা = চিরদিনের জন্য প্রস্থান; গোঁফ খেজুরে = নিতান্ত অলস; ডুমুরের ফুল = দুর্লভ বস্তু; উলুবনে মুক্তা ছড়ানো = অযোগ্যকে মূল্যবান জিনিস দেওয়া।

Physical Measurement Test (PMT) for male candidates typically requires height 167 cm (relaxation for hill-area and tribal candidates) and chest 78 cm with 5 cm expansion.

Female candidates' PMT standard is generally height 160 cm with relaxations for hill-area and tribal candidates; weight is recorded but the governing criterion is height.

Physical Efficiency Test (PET) for male candidates commonly includes a 1600 m run within about 6 minutes and a long jump of about 3.65 m or high jump of about 1.20 m.

Female candidates' PET commonly includes an 800 m run within about 4 minutes and a long jump of about 2.75 m or high jump of about 0.90 m.

Qualifying both PMT and PET is mandatory; the PET is qualifying in nature and marks are not added to the written examination total.

Candidates must carry the original admit card and photo identity; measurement is done barefoot, and chest measurement is taken in both normal and expanded states.

Fitness preparation follows progressive overload: build an aerobic base with 3-4 weekly runs, add interval sessions, and include strength work for legs and core.

Hydration and rest matter: drink water before and after runs, avoid heavy meals within two hours of a test, and taper training in the final week before the PET.
