What are some dives? (that I could do?)?

I'm on the dive team but I'm sorta new at it. So far I can do forward tuck dive and a backward straight dive. Of course I could also do a front jump and a back jump too. But I need another dive to be able to compete. I've tryed a front flip but I kept turning on my side and not tucking enough. Then I tryed a back flip but I tucked to soon so I didn't reach and ended up doing a backward cannon ball. I need to learn a new dive tomorrow but I don't know what!! Any easy ideas!!
