Help me calculate my GPA

<p>Hi,</p>

<p>I am a rising senior and my final gpa will be computed in late August. I can't wait that long. Every time I calculate my gpa I get a different average. I have 10 B's, 3 B-, 1 B+, 1 A+, 3 A-, 1 C+, and 1 C-. These grades are from 21.5 credits.
If anyone can compute this I would greatly appreciate it! Thank you!</p>

<p>If - and + counts as the same value, 3.1 UW
If a B- counts as 2.7 and B+ counts as 3.3, 3.04 UW</p>
