My first cheerleading competition, along with all of the practices and events leading up to it, was a nerve racking, yet extremely exciting experience.

I don't know if that is the right subject/verb agreement. It is a topic sentence for a narrative paragraph I have to write in paragraph writing class.

Yes, your subject and verb agree. Well done!

To determine if the subject/verb agreement in the sentence is correct, we need to consider the relationship between the subject and the verb.

In this case, the subject of the sentence is "My first cheerleading competition, along with all of the practices and events leading up to it." This subject is composed of two parts: "My first cheerleading competition" and "all of the practices and events leading up to it."

The verb in the sentence is "was." We can now assess if the subject and verb agree in terms of number and tense.

Regarding number, we need to consider whether the subject is singular or plural. In this case, the subject is singular because it refers to a single competition and all the related practices and events as a collective unit.

Now, let's check the tense of the verb. In your sentence, "was" is in the past tense, which is appropriate for describing your experience in a narrative paragraph.

Considering both the number and tense, we can conclude that the subject/verb agreement in the sentence is correct.
