SAMPAD Grade 10 Entrance Exam common mistakes
SAMPAD Grade 10 Entrance Exam · Understand the traps and how to avoid them.
In Mathematics, when a word problem gives a ratio (e.g. ages or mixture proportions) and asks for an actual quantity, the candidate sets up the ratio but then answers with the ratio term itself instead of multiplying by the scale factor to get the real value.
Ratio problems are introduced early and drilled as 'find x:y', so the habit of stopping at the reduced ratio persists. Candidates also skip the final substitution step because they feel the algebra is 'already done'.
What to do instead
After every ratio problem, force a final line labelled 'actual value =' that multiplies the ratio term by the scale factor and states the unit. Practise 10 mixed ratio problems where the answer must always be a real quantity with units, and reject any answer that is still a bare ratio.
In Mathematics, the candidate computes the value of an expression or solves an equation correctly but then ignores the sign, the units, or the direction of an inequality when selecting the option, e.g. writing x > 3 when the correct result after dividing by a negative number is x < 3.
Inequality reversal and sign handling are procedural rules that are easily dropped under time pressure, and candidates check only the arithmetic, not the transformation rules.
What to do instead
Before solving, write the rule 'flip sign when multiplying/dividing by a negative' at the top of the rough sheet. After solving, substitute one value from the answer interval back into the original inequality to confirm it holds, and do the same check for a value just outside it.
In Physics, the candidate substitutes numbers into a formula without first converting all quantities to SI units, so a distance in centimetres or a time in minutes is plugged in directly and the answer is off by a power of ten or sixty.
Textbook problems often state values in convenient units, and candidates memorise the formula but not the unit requirement. Conversion is treated as an optional tidy-up rather than part of the calculation.
What to do instead
Adopt a fixed three-step layout for every numerical physics item: list given quantities with units, convert each to SI in a separate column, then substitute. Circle any quantity not already in SI before starting the algebra.
In Chemistry, the candidate balances a chemical equation by changing subscripts inside a formula (e.g. turning H2O into H2O2 or CO2 into CO) instead of placing coefficients in front of the formulae.
Balancing is taught as 'make the atom counts equal', and adjusting subscripts is the fastest way to make counts match, so it feels correct. Candidates do not connect subscript changes to changing the identity of the substance.
What to do instead
Rule to write at the top of the page: 'subscripts are fixed; only coefficients change.' Practise by balancing 15 equations and, for each, writing the name of every substance before and after to prove identity is unchanged.
In Biology, the candidate answers 'what is the function of X' with a definition of X rather than its function, e.g. describing the structure of a nephron instead of stating that it filters blood and forms urine.
Definitions are the most memorised content, and under exam pressure the candidate reproduces the nearest stored sentence rather than reading the command word in the question.
What to do instead
Underline the command word (state, describe, explain, why) in every Biology question before answering. Train with a two-column drill: organ/part on the left, its function in one sentence on the right, and answer only from the right column for function questions.
In English comprehension, the candidate answers a passage question from general knowledge or personal opinion instead of from information stated in the passage, and writes a full sentence copied verbatim from the text when the question asks for a brief answer.
Passages are often on familiar topics, so the candidate's prior knowledge overrides the text. Copying whole sentences feels safe because every word is from the passage.
What to do instead
For every comprehension answer, point to the line number in the passage that supports it before writing. Practise paraphrasing: rewrite the supporting line in your own words in under 15 words, and use that as the answer.
In English grammar items, the candidate chooses the option that 'sounds right' for subject-verb agreement, tense sequence, or preposition use, without identifying the grammatical subject or the time reference first.
Everyday spoken English differs from standard written English, and candidates rely on familiarity. Long subjects with prepositional phrases (e.g. 'the list of items') mislead the ear.
What to do instead
For agreement questions, bracket and delete every prepositional phrase, then match the remaining head noun to the verb. For tense questions, circle the time word (yesterday, since, by next week) before choosing the form.
In General Knowledge and Current Affairs, the candidate relies on facts learned months earlier and answers with outdated officeholders, capitals of renamed entities, or superseded records and rankings.
Static facts and current facts are stored together with no freshness check, and candidates rarely revise the current-affairs portion after the initial reading.
What to do instead
Maintain a one-page 'dated facts' sheet listing officeholders, major appointments, and records with the month and year beside each entry. Revise only entries from the last 12 months weekly, and mark any fact older than a year as 'verify before trusting'.
In Logical Reasoning, the candidate reads only part of the conditions in a seating arrangement, ordering, or blood-relation puzzle and starts drawing the arrangement before listing all constraints, then cannot detect the contradiction when a later clue is added.
Puzzles reward speed, so candidates begin diagramming after the first two clues. Working memory holds only a few constraints, so later clues get ignored rather than integrated.
What to do instead
Number every clue in the question and tick each one off as it is placed in the diagram. Before finalising, re-read the numbered list and test the completed arrangement against each clue in order; if any clue fails, restart rather than patch.
In Bangla Language and Literature, the candidate confuses similar-sounding or similarly written words (জ/য, শ/ষ/স, ন/ণ, and common homophones) and answers grammar items such as sandhi, samas, or karak on the basis of sound rather than the rule.
Bangla spelling rules for these letters are learned by exposure rather than by a single rule, and the exam's grammar terminology (সমাস, কারক, সন্ধি) is often memorised as labels without the underlying classification test.
What to do instead
Keep a personal error log of every misjudged word with the correct spelling and the rule that decides it. For grammar items, state the classification question aloud (e.g. 'which word is the verb, which is the karak?') and apply the definition before selecting an option.
