How do interim or partial transcripts work for application, and is it possible to have an admissions decision reversed based on the final version?
You need to explore this with the institutions you apply to. 

And you need to read the correspondence carefully. If you get accepted, then you are probably accepted except in rare circumstances. But if you are "conditionally accepted" then you need to meet the conditions, whatever they are, to assure acceptance. 

Acceptances are generated based on more that GPA, of course. Someone needs to make a prediction of success before one will be issued. But no prediction is perfect and students fail out even after enrolling. Universities know these things. 

Tips and advice: Work hard. Don't let the bad things happen.
