With just days to go until the final, the group are on course for victory in the last of the live shows.
They'd be the first boy band to EVER win the show and only the second group after Little Mix in 2011.
After enjoying THREE Number 1 songs from their performances on the live shows, Rak-Su look unstoppable in the race for victory.
Their closest rival is Grace Davies who had been the early frontrunner.
She's promised more original songs in the final but it seems as though she's going to need to bring something out of the bag to beat the boys.
Joining the pair in this weekend will be Kevin Davy White, the outsider but not to be counted out.
The three are the ones left standing after five weekends of live shows, fewer than any other year.
16 made it to the start before a series of live performances and brutal elimination rounds decided the strongest.
This year there was no bottom two sing-off at all, with viewer votes alone deciding the winners and losers each weekend.
The first round saw two eliminations as Spencer Sutherland and Talia Dean went home after the first viewer votes. In Week 2, the Boys and Overs categories each again lost another act as Leon Mallett and Tracey Leanne Jefford were sent home.
In Week 3, the Girls and Groups lost their first acts as Alisah Bonaobra and duo Jack and Joel were voted off by the public. In Week 4, it was a quadruple elimination as Holly Tandy, Rai-Elle Williams, Sam Black and Sean and Conor Price were all voted off.
In the semi-finals, a trio went home with Matt Linnen, and The CutKevlins and Lloyd Macey all leaving.
Now one of the remaining three - Rak-Su, Kevin Davy White and Grace Davies - will be crowned the WINNER of The X Factor 2017 this weekend.
The X Factor will start on Saturday at 7:05PM with the first performances and return Sunday at 7:20PM with the last weekend of live singing.
