Matchless Raijin-Oh - Season 1 Episode 3 Tests Are a Huge Annoyance!?

The entire Class 5-3 average match score of the last test is far below the rest of the other classes and needs to do a retest. Asuka, Kouji, Maria and Tsutomu are assigned to help Jin with his studies as his test score is zero. Jin tries to run away, but in the end can't escape. The next day, right before the retest, Jaku Beast Testora appears and Class 5-3 needs to sortie. After defeating the Jaku Beast, Class 5-3 does the retest much to the dismay of Jin. A couple of days later the tests are graded and Jin has 80 points.
