Many students find it difficult to use 'so that' and 'so as'. In this post, I would like to show readers how to use them correctly.
1 'so that' is followed by a clause
Example 1:
You must study hard so that you can pass the exam with flying colours.
Example 2:
The fat lady needs to exercise so that she can remain slim all the while.
Example 3:
The teacher speaks slowly and clearly so that her students will be able to understand her lessons.
[A clause consists of a subject and a finite verb.]
2 ‘so as’ is followed by an infinitive.
Example 1:
John works hard so as to earn a lot of money.
Example 2:
She copied the text carefully so as not to make a single mistake.
Example 3:
He studies hard so as to pass his exam with high grades.
