Sorry - it obviously stinks any time someone has a death in the family - but writing this, in my opinion, will likely be ignored but potentially can be seen as excuse making.
The grades are the grades - and they’re not bad btw. But the student owns them.
You didn’t suffer in all your classes - and you will learn in life, no one is perfect. You cannot tie getting Bs to being out. You may have gotten them anyway.
No school says they are a 3.9 UW and not a 4.0 and therefore they’re gone - and that’s what you’re surmising. So I would stop that thought process.
They will look at much more - rigor, ECs, other traits, the essays, the recs.
There’s really not an issue here - you’re creating one that doesn’t exist (in my opinion).
Good luck.
