RBI Security Guard common mistakes
RBI Security Guard · Understand the traps and how to avoid them.
Spending the first 15–20 minutes on General Awareness questions about current appointments and sports results, then rushing the reasoning section with 10 minutes left.
General Awareness feels easy because the questions are short, so candidates answer them first and lose track of time; they do not realise that each GA question still costs 30–45 seconds of recall or guessing.
What to do instead
Do a timed mock with a fixed order: Reasoning (25 min), Numerical Ability (25 min), English (15 min), General Awareness (10 min), leaving 5 min buffer. In GA, if the answer does not surface within 20 seconds, mark it and move on; return only after all sections are attempted.
Guessing on GA questions about RBI history and functions without eliminating options, e.g. picking 'Reserve Bank of India Act, 1934' versus '1935' at random instead of recalling that the Act was passed in 1934 and the Bank began operations on 1 April 1935.
Candidates memorise isolated dates without the surrounding story, so under exam pressure the facts blur and they treat closely related years as a coin toss.
What to do instead
Build a one-page timeline: RBI Act 1934, RBI opened 1 April 1935, nationalisation 1949, first Governor Osborne Smith, first Indian Governor C.D. Deshmukh, headquarters shifted from Kolkata to Mumbai in 1937. Revise this sheet weekly until the sequence, not just the numbers, is fixed.
In Reasoning, attempting every puzzle and seating-arrangement set in full, including the one with five variables, instead of scanning and choosing the two solvable sets.
Candidates believe leaving a puzzle blank is a waste, so they sink 8–10 minutes into one arrangement and lose three easy questions elsewhere.
What to do instead
Practise a 90-second scan rule: read all sets first, tag each as 'direct' or 'complex', solve direct sets completely, and abandon a complex set after 3 minutes if no fixed position has emerged. Track how many marks this recovers in mocks.
Losing marks on inequality and syllogism questions by drawing full Venn diagrams for every statement instead of applying the standard possibility rules.
School-style diagramming is slow, and candidates have not drilled the 'either-or' and 'possibility' cases, so they second-guess correct answers.
What to do instead
Learn the priority order for conclusions (definite, possibility, either-or) and practise 30 inequality questions and 30 syllogism questions in one sitting, writing only the conclusion chain, not diagrams. Aim for under 40 seconds per question.
In Numerical Ability, solving simplification and approximation questions with full written calculation, including long division for percentages like 37.5% of 896.
Candidates revise arithmetic by doing textbook sums on paper, so they never build the fraction-to-percentage reflexes the exam rewards.
What to do instead
Memorise the standard fraction table (1/8 = 12.5%, 3/8 = 37.5%, 1/16 = 6.25%, etc.) and practise 20 approximation questions daily with a strict 30-second limit, using rounding to the nearest convenient fraction rather than exact division.
Skipping Data Interpretation sets entirely because the table or bar chart looks large, then losing the 5 marks that come as a block.
Candidates fear calculation volume, but DI questions usually test ratio, percentage change, and average, which are quick once the numbers are read correctly.
What to do instead
Do one DI set daily: read the title, units, and headings first, then answer only the two easiest sub-questions before attempting the rest. Practise percentage-change shortcuts (difference divided by base, scaled mentally) so each sub-question takes about 60–75 seconds.
In English Language, reading the entire passage before looking at the questions, then re-reading it for each question.
This is the habit from school comprehension tests, and it doubles reading time in a section where questions are mostly vocabulary, error spotting, and fill-in-the-blank rather than deep inference.
What to do instead
For cloze and fill-in-the-blank items, read the sentence with each option substituted and choose by grammar and collocation first. For reading comprehension, read the questions first, then scan the passage once, underlining only the lines that answer them.
Choosing English options by how formal or long they sound rather than by grammar, e.g. selecting 'He is one of the best officer who has served' over the correct singular/plural agreement.
Candidates lack practice in spotting subject-verb agreement, preposition collocations, and article use, so they rely on intuition, which is unreliable under time pressure.
What to do instead
Maintain an error log of 5 rules per week (one of + plural noun, each/every + singular verb, since/for, articles before unique nouns) and rewrite each incorrect sentence correctly by hand. Review the log before every mock.
Ignoring the negative-marking and sectional-timing rules stated in the actual exam instructions, then attempting 100 questions with 40 wild guesses.
Candidates prepare from memory of a previous pattern and never read the instruction sheet, so they do not know whether wrong answers cost marks or whether sections are individually timed.
What to do instead
In the final week, read the official instruction page of the current notification twice and simulate those exact rules in two full mocks. Set a personal guessing threshold: attempt only if at least two options can be eliminated.
Preparing General Awareness only from month-old current-affairs compilations while skipping static banking awareness (RBI roles, monetary policy tools, currency issuance, banking terminology).
Current-affairs PDFs are easy to download and feel productive, but this exam draws heavily on stable facts about the RBI and basic banking, which are rarely revised.
What to do instead
Split GA revision 50:50 between static banking/RBI facts and current affairs. Cover the RBI's functions (currency issue, banker to government, lender of last resort), CRR, SLR, repo and reverse repo, and basic terms such as NEFT, RTGS, and KYC, revising one topic per day with self-written one-line definitions.
