You can still earn marks if your <strong>Method<\/strong> is clear, your <strong>Observations<\/strong> are accurate, and your <strong>Results\/Calculations<\/strong> show correct working and appropriate units. Precautions and understanding also help.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_How_many_precautions_should_I_write_in_WAECNECO_practicals\"><\/span>2) How many precautions should I write in WAEC\/NECO practicals?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Write about <strong>3\u20136<\/strong> relevant precautions.

If something is unclear, write what you can confirm.
