Need advice

Hi everyone, I'm currently in 12th standard. By March, my examinations will be over. I want to work as a cabin crew. But my results will be out by May and i don't want to wait till May. Can I go for walk in interview without my 12th result? For reference I got 84 percent in 10th and 78.5 percent in 12th 1st semester. So it's certain I'll get more than 50 or 60 percent in 12th. So my question is can I go for the walk in interview with just 1st semester results and tell them I'm awaiting results? (One of my sister who works in emirates as a cabin crew told me this).
