Grammar and word usage

Is it correct?

* I always utilized ACT Sparknotes as a source
* The students were interested to learn.

Let's break down the sentences and analyze them for grammar and word usage:

1. "I always utilized ACT Sparknotes as a source."
The sentence is grammatically correct. However, the word "utilized" is more formal and less common in everyday speech. A simpler alternative could be "I always used ACT Sparknotes as a source."

2. "The students were interested to learn."
This sentence has a grammatical issue. The word "interested" should be followed by the preposition "in" instead of "to." The correct version would be "The students were interested in learning."

By analyzing these sentences, we can ensure that our grammar and word usage are accurate and effective.
