1. HOW TO SCORE MAXIMUM IN BIOLOGICAL DIAGRAMS

2. INTRODUCTION
Knowing the appropriate ways of drawing a biological diagram can really improve a student’s
overall performance in the subject.
The following rules can come in handy for you.

3. RULE 1
Draw what you see, NOT what you WANT to see. Do not improvise in any possible manner. It
might seem a bit harsh, but you should know that there’s no room for creativity in biological
drawings.
RULE 2
Make sure you use a good quality pencil for your diagrams. 2H pencils are more advisable, but
you may also use technical drawing pencils for your biological diagrams.

4. RULE 3
Try to make your diagrams as simple as possible. And avoid sketching your diagrams at all
possible cost. Use clear cut lines for your diagrams and that's it.
RULE 4
Make sure you draw your diagrams on unlined sheets, especially when doing a lab copy for your
biology practical examination.

5. RULE 5
As far as labeling is concerned, follow the following rules as closely as possible for more
efficiency:
Labeling should be done in a column at the right-hand side of your page. Also, try to maintain an
alignment.
Always use a scale for drawing the lines used for labeling purposes and keep these lines parallel
to one another.
The lettering used for labeling should be kept in horizontal alignment. Try to avoid vertical
lettering unless you are specifically instructed to do so.
Keep your lettering neat such that the observer can understand it in a jiffy. Use block letters if
possible.

6. RULE 6
Avoid crowding parts of the diagram. Things like that can make you lose marks.
RULE 7
Keep your diagram to the left. Use the right-hand side for labeling purposes.

7. A FEW WORTHY MENTIONS...
All biological drawings should be titled.
Avoid shading your diagrams.
Try to draw on a single stroke of the pencil.
Labeling intersections aren’t tolerated. Avoid.
