Skilled worker immigrants - english classes

Just asking this question for one of my friends. She immigrated to Canada as a skilled worker a couple of years ago. Stayed for a little while, and then returned to her home country to finish up a few things. Now she is back to Canada again and this time she is gonna stay permanently. As a skilled worker, she is not sure whether or not she is eligible for taking those gov't sponsored English classes (LINC, ESL, etc.). Her logic is that she submitted an English test score to cic when she applied to become a PR, so she had already demonstrated her English language ability. If she now decides to take their classes, they may not accept her on the grounds that she knows enough English already. She reads well, but she wants to improve her English level in terms of speaking and listening.

I have never had to take those classes so I have no clue. Are you guys familiar with this matter?

Thanks.

Did she keep a copy for her English test results that she submitted to PR application? If so, CIC will accept a photocopy of it for citizenship without having to take another test.
