You should not put the cart before the horse, in the sense of, if you're accused of falsifying the results on a college project. The question would be, did you in fact falsify the results, or is it just a matter of, say, interpretation? Professors are unfortunately often too quick to accuse a student of misconduct because they simply may not agree with what was submitted. They may not understand the results and a professor often is looking at it through their lens solely.
Obvious they're highly experienced in the field, and they may not understand why a student who is still learning would produce certain results, and by that being the case, they would assume that the student is responsible for some kind of misconduct when that, in fact, may not be the case. In terms of what's appropriate to the circumstances, it will, of course, depend on what either took place or did not take place.
In terms of what potential outcomes could be, if somebody is found responsible, it can vary, it can be anything from probation, suspension, expulsion, it could be a warning. You cannot depend on the school or the professor to necessarily do the right thing. Taking the necessary precautions before you engage with the school in any capacity is incredibly important. Having an experienced academic misconduct attorney advisor will be your best ally to help you understand and navigate the process.
