problems in CBT are actually <em>working<\/em> problems. Common causes include:<\/p>\n<ul>\n<li><strong>Careless arithmetic:<\/strong> wrong additions\/subtractions in the middle of calculations.<\/li>\n<li><strong>Order-of-operations errors:<\/strong> ignoring the standard sequence for brackets, indices, division, multiplication, addition, and subtraction.<\/li>\n<li><strong>Unit confusion:<\/strong> mixing centimetres with metres, or misreading percent\/fraction relationships.<\/li>\n<li><strong>Guessing too fast:<\/strong> selecting an option without a final check.<\/li>\n<li><strong>Last-minute answer switching:<\/strong> changing because you \u201cfeel\u201d uncertain instead of verifying your working.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"The_JAMB_CBT_scratch-pad_system_simple_steps_you_can_repeat\"><\/span>The JAMB CBT scratch-pad system (simple steps you can repeat)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The scratch-pad system is not about writing the full solution. It\u2019s about writing only what makes your calculation <strong>clear, checkable, and quick<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_Convert_the_question_into_a_mini-equation\"><\/span>Step 1: Convert the question into a mini-equation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When you read the question, quickly capture the core information in a compact form. This reduces the need to reread the text and prevents you from missing a key value.<\/p>\n<p>Use formats like:<\/p>\n<ul>\n<li><strong>Percent:<\/strong> write the conversion you will use, e.g., <strong>20% of 250<\/strong> \u2192 <strong>20% \u00d7 250<\/strong><\/li>\n<li><strong>Algebra:<\/strong> write the equation you are solving (focus on the equation, not long explanation)<\/li>\n<li><strong>Ratios:<\/strong> write ratio and any totals, e.g., <strong>A:B = 3:5<\/strong>, <strong>total = 80<\/strong><\/li>\n<li><strong>Physics kinematics (if applicable):<\/strong> tag the key values (often with units) such as <strong>v, u, t<\/strong> (and <strong>s<\/strong> if needed)<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_Do_one_%E2%80%9Csafe%E2%80%9D_intermediate_step\"><\/span>Step 2: Do one \u201csafe\u201d intermediate step<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Instead of trying to finish the entire problem in your head, do one step that removes ambiguity\u2014then continue. Examples of safe intermediate steps:<\/p>\n<ul>\n<li><strong>Convert percent to fraction:<\/strong> <strong>25% = 25\/100 = 1\/4<\/strong><\/li>\n<li><strong>Convert mixed units:<\/strong> <strong>60 cm = 0.6 m<\/strong><\/li>\n<li><strong>Rewrite powers\/roots clearly:<\/strong> if needed, simplify forms before calculating<\/li>\n<li><strong>Apply indices rules:<\/strong> e.g., <strong>a<sup>m<\/sup>\/a<sup>n<\/sup> = a<sup>m\u2212n<\/sup><\/strong><\/li>\n<\/ul>\n<p>This single \u201csafe\u201d step often prevents the biggest mistakes, because it corrects your interpretation early.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_3_Use_unit_tagging_before_you_select_an_option\"><\/span>Step 3: Use unit tagging before you select an option<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Before clicking the answer, do a quick glance at your units and the direction of your result. For Maths\/Physics-style questions, unit logic helps eliminate wrong choices that look close.<\/p>\n<p>Examples of what to check:<\/p>\n<ul>\n<li><strong>Distance:<\/strong> if inputs are in metres, your distance result should be in metres.<\/li>\n<li><strong>Speed:<\/strong> since speed is distance divided by time, your unit should match that idea (for example, <strong>m\/s<\/strong> if using SI inputs).<\/li>\n<li><strong>Percent-change questions:<\/strong> ensure the value you compute corresponds to the correct base (original value).<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Step_4_Perform_a_fast_sanity_check_%E2%80%9Cdoes_this_make_sense%E2%80%9D\"><\/span>Step 4: Perform a fast sanity check (\u201cdoes this make sense?\u201d)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A sanity check is a short verification using reasoning\u2014not extra heavy calculation. Choose one quick check:<\/p>\n<ul>\n<li><strong>Magnitude check:<\/strong> If the question suggests a \u201csmall\u201d outcome but your result is huge, you may have multiplied instead of divided.<\/li>\n<li><strong>Sign\/direction check:<\/strong> In many motion and word problems, certain quantities should logically be positive.<\/li>\n<li><strong>Approximation check:<\/strong> estimate quickly to see whether an option is in the same ballpark.<\/li>\n<\/ul>\n<p>For example, if you know <strong>19 \u00d7 4<\/strong> should be around <strong>76<\/strong>, you can eliminate options far away from that estimate.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%E2%80%9CCalculator_mindset%E2%80%9D_for_JAMB_CBT_without_relying_on_a_calculator\"><\/span>\u201cCalculator mindset\u201d for JAMB CBT (without relying on a calculator)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Even if you are not using a calculator in the CBT hall, you can think like one: write steps, keep your order controlled, and avoid skipping arithmetic. This reduces wrong answers caused by mental shortcuts.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Follow_the_consistent_order_of_operations\"><\/span>1) Follow the consistent order of operations<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Use a stable rule for handling expressions. A commonly taught approach is:<\/p>\n<ul>\n<li><strong>B:<\/strong> Brackets<\/li>\n<li><strong>I:<\/strong> Indices (powers)<\/li>\n<li><strong>D:<\/strong> Division<\/li>\n<li><strong>M:<\/strong> Multiplication<\/li>\n<li><strong>A:<\/strong> Addition<\/li>\n<li><strong>S:<\/strong> Subtraction<\/li>\n<\/ul>\n<p>Before you choose an answer, ask: <strong>Did I handle powers and brackets first?<\/strong><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Use_%E2%80%9Cchunking%E2%80%9D_for_large_numbers\"><\/span>2) Use \u201cchunking\u201d for large numbers<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When calculations are heavy, break them into manageable parts. The goal is not speed-for-speed\u2019s sake; it is reducing arithmetic slips.<\/p>\n<p>You can mentally split large numbers into simpler differences or parts (the exact strategy depends on the question). What matters is that you avoid one long chain of mental arithmetic that can easily go wrong.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Use_percentfraction_conversion_shortcuts\"><\/span>3) Use percent\/fraction conversion shortcuts<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Percent and fractions appear frequently in CBT questions. Keep conversion rules simple:<\/p>\n<ul>\n<li><strong>Percent to fraction:<\/strong> <strong>p% = p\/100<\/strong><\/li>\n<li><strong>Fraction to percent:<\/strong> <strong>(numerator\/denominator) \u00d7 100<\/strong><\/li>\n<li><strong>Avoid decimal traps:<\/strong> if possible, keep the fraction form until the last step<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"4_Dont_trust_your_%E2%80%9Cresult_brain%E2%80%9D_without_checking\"><\/span>4) Don\u2019t trust your \u201cresult brain\u201d without checking<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Even when you do calculations using paper, avoid selecting instantly. Use a final micro-check:<\/p>\n<ul>\n<li>Re-check the arithmetic once.<\/li>\n<li>Confirm you matched the question requirement (for example, <strong>find x<\/strong> vs <strong>find 2x<\/strong>).<\/li>\n<\/ul>\n<p>This prevents the CBT error where you answer a different quantity than what the question asked.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Avoid_the_%E2%80%9Clast-minute_answer_switch%E2%80%9D_problem\"><\/span>Avoid the \u201clast-minute answer switch\u201d problem<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Many candidates change answers when uncertainty appears.
