As part of the exam preparation the CBSE board exam students must learn to draw neat diagrams as well. Here are some tips to handle the Biology diagram-based questions properly and may help to score higher marks in board exams.
Use an extra bold lead pencil to make the diagrams. Never draw diagrams with a pen so that in case of any error, the students can erase it and re-draw it neatly.
Try practicing the diagram at home while preparing for board exams. This would help the students become confident about their drawing skills and make an error-free diagram in the actual board exam.
In case of any error, try to erase the diagram properly without leaving any old pencil marks on the sheet to avoid any confusion for the examiner.
Position the diagram on the left side of the answer sheet and the labelling on the right side of the answer sheet.
In case of complicated diagrams having multiple labels, number each of the parts and then separately write the labels below the diagram against the correct number. Do not intersect the labelling lines.
Make sharp lines instead of soft lines while drawing the diagram and keep its size large enough to label it properly. Avoid making more than two diagrams on a single page.
Represent darker areas of a subject with dots than shading them
The first part of a scientific name must be capitalised and the second part to be in lowercase
Always give a title to the diagram to make it clear what does it represents
