Translation:The students will learn in the class but I will not learn.
You can hear the root word foghlaim pronounced on Duolingo in the exercise Tá mo mhac ag foghlaim na Gaeilge, though it's worth listening to the different pronunciations on teanglann.ie too - the Munster pronunciation is noticeably different.
The future tense 1st person plural Foghlaimeoimid is also spoken in this exercise, but it's probably not of much help to you.
"sa" means "in the".
The English phrase "in class" is usually translated into Irish as "sa rang", but when translating in the other direction, from Irish to English, "sa rang" is usually translated as the literal "in the class", unless the context clearly indicates that that would be wrong, which isn't the case here.
