We can say that Stuttgart's fixtures were not easy. They will play against both Bayern, Leverkusen and Dortmund in the next month. If they manage to win these matches, they can pass Bayern and get into second place, but I don't think that can happen.
I think Stuttgart played better than expected and managed to stay in the top 3 teams until the end of the season. I think their goal is to maintain their current ranking
Well, it will be a tough schedule for Stuttgart and I'm pretty sure they will fight it out in these three matches. They must at least not lose a single point and if necessary Stuttgart must hold on to a draw rather than not scoring any points at all. The toughest challenges for them are against Bayern Munich and Leverkusen, but against Dortmund I believe they can take 3 points.
The job will be even more difficult because they have to compete with these teams at the top and the condition for them to be able to maintain their current position is not to lose. Maybe on the other hand, if Stuttgart loses the match against Bayern Munich and Leverkusen, then Dortmund has the opportunity to shift them from 3rd place in the standings.
