It is common to hear people say "I am at school" or "I'm in school". Both phrases are used to communicate that the speaker is currently studying or attending a class at school. The choice between the two is largely a matter of personal preference. Generally, the phrase "I'm at school" implies that the person is present at the school premises and is actively engaged in an activity, while "I'm in school" implies that the person is enrolled in a school, but may or may not be physically present on school premises. Ultimately, both phrases are acceptable, but the context in which they are used should be taken into consideration.
