Gleeks, the day is almost here! After what seemed like an interminably long summer vacation, McKinley High is back in session Tuesday night when Season 3 of 'Glee' premieres at 8PM ET on Fox.

Thankfully, we don't have to wait that long to get a glimpse of the episode. AOL TV got scoop on the new season from Ryan Murphy at a screening last week, we heard all the songs from the episode on Friday, and now several clips from the premiere have been released online. Below, a look at all of the Season 3 sneak peeks.

First, enjoy the first 36 seconds of the episode over at TV Guide, with the intrepid Jacob Ben-Israel roaming the McKinley halls and casually finding out that both Tina and Artie are juniors, not seniors.

Second, head to Deadline to see the first political-themed edition of Sue's Corner to see how Sue Cs arts education in schools.

Finally, Entertainment Weekly has the full video of one of the premiere's five musical numbers, 'We Got the Beat,' in which the New Directions channel the kids from 'Fame' in a cafeteria singalong. Bonus: First glimpses at the new characters played by LaMarcus Tinker and Vanessa Lengies. Check out the video below, but visit EW for a high-quality version.



'Glee' Season 3 premieres Tue., Sept. 20 at 8PM ET on Fox.
