@SJ-Sil80 Sorry about your frustration with your recruiter. I'll give you my 2 cents here and if history proves right, a few recruiters on here will be quick to correct me, whether they are correct or not. When it comes to your GPA, the way they did it is correct. It has to be a cumulative GPA from ALL sources. We have to get all transcripts post-high school and use their quality point scheme and then do a calculation with all transcripts to come up with a cumulative. Most often, this works against the applicant but it's the rule. As for re-applying, you can either wait 6 months and re-apply or change at least one thing of significance in your application. For most, that's the test. There are some other things, too, but the test is the lowest hanging fruit to tackle. A new, revised motivational statement will be needed and if you've changed/added any activities, you definitely want to update page 2 of your application.
Best of luck to you!
