The subject John agrees with the verb is. In this case said can go with the word is. After reading this sentence it seems as if he is currently taking the course and that is why the present tense is, is being used.
Hopefully this helped and good luck.

Answer: What I learned about Leopard seals. The reason why Leopards seals are called '' Leopard seals" is because they have a black spotted coat, which are similar to the famous black cat. They're the third largest seal in the world! Leopards sing when they're underwater. Their vocalizations are often described as “trills” and “hoots” and consist of short-distance “local calls” as well as long distance “broadcast calls” Leopard seals don't have many predators, but they can be very dangerous to humans. The cutest thing they sometimes do is.... they smile!
