Low GPA - HBX Core to Compensate - Are all Classes/Programs created Equal?

Hey All,

I have a low GPA (3.11) with a downward trend. No point getting into the reasons why in this post. Anyone who has read Accepted's MBA Admissions Tip: Dealing with a Low GPA knows that the most important part of mitigating a low undergraduate GPA is developing a convincing story, but when it comes to taking extra classes to bolster your academic record - I have some questions about HBS Online CORe:

1. Based on what I've read on this forum, HBX CORe seems highly regarded. However it grades classes on an augmented pass/fail structure . Would it be better to take traditional coursework where I have a shot of achieving an "A"?

2. Would M7 Adcoms consider additional coursework at HBS CORe different than traditional Accounting/Finance Coursework at MIT vs BU vs Suffolk vs UMASS Boston? Would they hold coursework at more prestigious universities in higher regard?

3. A lot of the advice I've found online seems to emphasize that "Recent" coursework is needed to offset a low GPA. Any thoughts on if there is an optimum time to take the classes? i.e., are classes taken 1 year before applying regarded higher than if taken 3 years before applying regarded?

4. I have a significant tuition reimbursement program at work (maybe enough for 4/5 individual courses). Outside of HBS CORe - are there any other beneficial courses I could take to use up the rest of my allowance?

I have a feeling I'm over analyzing this - just wondering if there are ways to optimize this aspect of my preparation.
