At Rintis Island Primary School, Papa Zola plans to distribute the math test that already held on. Many student were frightened and cannot speak anything. Yaya and Ying were shown their rivalry again. Shockingly, Papa Zola mentions Gopal to be the umber 1 student. Gopal was happy, but he was number 1 at the back, which means that he failed. Then he fainted, then he also mentions that Fang was the number one student. Fang was happy and arrogantly insult BoBoiBoy because he is now eager to be more popular. Yaya and Ying were angry and try to scold him. Panicked, Fang was seen hiding behind BoBoiBoy. Actually, similar to Gopal, he also failed at his test and only got 39%.
