|How many seasons did the show last? |
The show ran for 7 years, however the series was produced for 6 years. The final two seasons were filmed at once and latered aired as two seperate years. This was also done for Hang Time and City Guys, which had 2 years split into 4 years.
|What was wrong with the 3rd season? |
Many episodes were just written with no respect to time line. The cruise episodes could only happen during the Spring semester since earlier episodes featured events that could only happen during the fall semester. This was also the final season to feature geeks and jocks as the background student body. Also so reoccurring characters stop appearing after this season.
|Is Bayside HIgh School real? |
Yes, there is a Bayside High School in Bayside, California. Valley High School also is real, however it is located in Sacramento and couldn't be a real life rival of Bayside.
|How many years had past since Zack and his friends left Bayside? |
None. Only a few months had past before this series began. Screech was in his second year of college when he returned in season 2. Thus the series took place in real time.
|What grade is everyone in? |
It was never made clear what grade the kids were in. The season one kids had to attend Bayside when Zack and the others were there. They would have to be Sophomores when this series started. Season 2 would have been Junior Year and Season 3 would have been Senior Year. Even with the cast changes, this would have worked out with Tommy and Lindsay being the last of the original cast to leave before Season 4. Thus leaving the others as Sophomores in Season 4, Juniors in Season 5 and Seniors in Seasons 6-7.
|Why did everyone know each other despite not appearing together in the previous season? |
One is left to assume that the kids had different classes. Although how could anything football related be done in Season 3 with Eric, who didn't appear until Season 4 and was on the football team.
|Did any other series take place in this universe? |
Yes, Hang Time shared the same universe as Saved by the Bell: The New Class. California Dreams may have taken place in the same universe since the school was mentioned in Season 1.
