How is the verb "wiederhole" conjugated and what tense is it in?

The verb wiederhole is the first person singular present tense form of the verb wiederholen. This means that the sentence is stating a current action: "I repeat."

Why is the article "den" used before "Plan" instead of "der" or "das"?

In German, the article you use depends on the noun’s gender and its grammatical case. Plan is a masculine noun. When a masculine noun is the direct object of a sentence—that is, when it’s in the accusative case—the definite article changes from der (nominative) to den (accusative). Hence, we have den Plan.
