will i get into trouble?

That's incredibly stupid. The difference between 3.7 and 3.8 is so marginal, it doesn't warrant any risk of failing background check, however negligible.

so i'll fail the background check?

Yea, probably, and then you'll get black balled jeffery Chiang style...

3.74 rounded to 3.8 is fine lol......

Was your GPA ever 3.8- and is this just an old resume? Do you plan on graduating with a GPA above 3.75?

I think the difference between 3.74 and 3.8 isn't that material, and for the sake of conservativism, would put a 3.74 on there instead. But you can argue it's kind of a gray area if you were getting a 3.752 last semester. If that's the case and the resume is already in, I would roll with it- I don't think that difference will be actionable enough to have an offer pulled.

You're fucked. Your best bet is to call the CEO directly and apologize profusely for your transgressions.

I'd be more offended if you didn't round up.

This shit just pisses me off. I have interviews coming up with a couple a top MM/ lesser BB and I have a 3.1. Everyone I talked to at the firms said they usually throw out resumes under 3.6. Plus, I had to send in my transcripts so that they could peruse all my shitty grades. What on earth compelled you raise your GPA from a 3.7 to a 3.8?? Just put 3.74, the difference is so marginal.

If you network and show enthusiasm for the job, you shouldn’t need to lie like this.

With that said, I doubt they would fire you for it. They may talk to you about it though (embarrassing).

You're screwed.
