For many learners of science, they struggle to express what they have 
understood of abstract science concepts into structured and 
congruent answers. As such, they often ended up not being able to 
score in examinations.
 
 To help my tutees (from primary to secondary levels), I have come up with 
the acronym 'DECAL' as a fail-proof way of helping those who need a 
'formula' to practise answering structured questions with.
 
 In these videos, I model how YOU can use 'DECAL' to help 
yourself (or your child).
 
 Try it and let me know how it works out for you!
