Former Motley Crue (search) drummer Tommy Lee (search) said he's finding his experience at the University of Nebraska-Lincoln (search) to be a lot of work.

In a news conference Sunday, Lee said he loves horticulture, but finds chemistry to be unbelievably hard.

Another shock: Learning he had to wake at 6 a.m. to be at Memorial Stadium for drum practice with school's band.

"This is the total fish-out-of-water experience for me," Lee said. "I didn't have the opportunity to go to college. I was busy touring since the age of 17. So this is completely strange and bizarre, but a lot of fun and a lot of work."

Lee, 42, is attending classes and activities during the filming of an NBC reality show, "Tommy Lee Goes to College." Filming began in early October.

"It's the real deal," Lee said of his studies. "I'm playing catch-up since we jumped in (during) the middle of the semester."

The "Smokin' in the Boys Room" rocker said he really is buckling down.

Executive producer Eddie October has even stored a picture in his cell phone of a sheet of paper he found taped to Lee's door last week. On it is written: "Do Not Disturb. Tommy is Studying (Seriously)."
