Is the test today?
Can you tell me if the test is going to be today (1)? I asked myself if I needed to study (2). I’ll study harder if the test is today (3). I don’t recall if the teacher said the test was today or tomorrow (4). If the teacher calls you (5), send me an e-mail. I’ll leave early if I don’t hear from you (6). Does anyone know if she called (7)? I wonder if we can leave early (8). If we leave early (9), I’m not sure if we can take the test tomorrow (10).
