The sentence you provided is not a run-on sentence. It appears to be a correct sentence in terms of grammar and punctuation. However, to confirm this, we can break down the sentence and analyze it further.

The sentence consists of multiple independent clauses:
1. "Grammar quizzes can be tough"
2. "There is a lot to learn"
3. "It is hard to remember"
4. "I find that it gets easier with practice"

Each independent clause is separated by a comma, which is appropriate in this case because the clauses are closely related and the information flows logically. Additionally, the coordinating conjunction "and" is used to connect the second and third clauses.

In terms of grammar, there are no obvious errors in the sentence. It is grammatically correct and conveys the intended meaning.
