Identify the type of sentenceI passed the test, but I would have gotten a perfect score if I had studied for their vocabulary section.

Explanation

This type of sentence combines features of both compound and complex sentences. It has at least two independent clauses and at least one dependent clause. Here, we have two independent clauses connected by "but" "I passed the test" (implied) "This is not a perfect score" The second clause ("would have gotten a perfect score if I had studied for their vocabulary section") is a dependent clause because it's hypothetical and relies on the first clause for meaning.
