GRAMMAR

 Conditional Type 0

If / When

Use to express a scientific fact

When we use "IF", we use the comma to separe the cause and the effect and we can use "WHEN" instead if.

For example:

If you dont make you blog, the pretty teacher Woodward will be mad..

When you dont have participation on class you will not have the exam

If i dont clean my room, i cant go out on weekend

When i put attetion on the class, i learn better

If my boyfriend didnt come to visit me, i will be mad, very mad.
