Someone please check my spanish work? My teacher says it's wrong and has returned it to me. 10 pts!!!?

I can't correct your Spanish, but it sounds like he just wants you to practice using the future tense. You used ir + infinitive in A4. And in B1, B2, and B3, you mistranslated the English sentences: in English it gives you the future tense (will + verb), not "going to verb". You should translate that into the future tense in Spanish, not ir + infinitive (which would be a translation of English's "going to verb").
