Fourteen year old Roni skipped two grades - straight in to her older sister Michal’s class. Now they are starting high-school together. It’s the worst thing that could ever happen to Michal and the coolest thing that can happen to Roni! Every big brother or big sister that has ever been tasked with looking after their younger relation will be able to identify with the situations depicted in "My Sister Skipped a Grade"; the need to forge your own identity and friends while having someone tagging along.
The new season, the longest yet with 16 episodes, will continue to follow Michal (Maya Bakowski) who has to deal with the presence of her younger genius and proud sister (Bar Minialy) in the same high school classroom as her. What can we expect? We can't tell you everything in advance, but we can tell you that: her mom (Tali Oren) makes the two girls share a room; Ronnie finds a new love (!!!); Michal is promoted to shift manager at the café (this way she can cause less damage) and she picks Dishi (hearthrob Omer Hazan) to work with her as a waiter. Koby (Amit Moreshet) loses his coat and becomes a nice guy! (But don't worry, it'll pass). The season also includes a special episode featuring the members of the Formula Band playing themselves and performing together with the actresses a song written especially for the show.
