Answer 1

1. I am your student from last year. <b>Somewhat OK</b>

2. I was your student from last year. <b>No; remove "from" and it'll be fine.</b>

3. I am your student last year. <b>No. The verb is in present tense, so "last year" doesn't make sense.</b>

4. I was your student last year. <b>This one's the best!!</b>

5. I am your student of last year. <b>It's OK, but #4 is perfect!</b>
