infinitives of purpose

When we want to talk about someone's purpose (the reason they do something), we can use:

• We can also express the same idea using so (that).
✓ I went to university so (that) I could avoid getting a job!

• With a negative purpose we don't normally use the full infinitive on its own.
✓ I went to university in order not to get a job!
✓ I went to university so as not to get a job!
✘ I went to university not to get a job!
