Don't spread stuff like that around, you're going to cause a panic.
If you get a below a 2.5 for a term gpa, you get a conditional event. Generally just a meeting with your instructor that goes on file. Not a real big deal, until you hit 3 conditional events. I got one the summer after my freshman year. HOWEVER, the OP said that they are a 200 going to FT. This is the one semester where getting below a 2.5 term actually means some bad things. If you get a 2.5 term the semester before you go to FT, you are not allowed to contract as a POC. You can go to FT and come back, but you are considered a "pursuing student". You will not be contracted or be able to receive a stipend. You will have one semester to achieve a TGPA of above a 2.5. If you fail to do this you will be dis enrolled from AFROTC.
Directly from the AFROTCI 36-2011:
"Cadets must meet minimum CGPA requirements to compete for an EA (reference Attachment 13 and Chapter 8 of this instruction). Non-contract cadets must have both a TGPA and CGPA of 2.5 to contract into the POC. Non-contract cadets will lose their previously awarded EA if they fail to achieve a CGPA of 2.5 by the end of the Spring semester. However, non-contract cadets are authorized to attend FT if they have a CGPA of 2.5 or greater yet they have a substandard Spring TGPA. Upon successful completion of FT, non-contract cadets are placed in pursuing status for one semester to meet the TGPA standard. Failure to meet the TGPA standard within one semester will result in dismissal. Contract cadets who do not meet Spring TGPA standards are awarded a CE IAW Table 4.2 and processed for disenrollment IAW Table 4.1 if necessary; otherwise they enter the POC upon successful completion of FT. Contract cadets are not authorized to attend FT while undergoing a disenrollment investigation."
*Question: Is physics a class you must recieve a C or above in? If it is you should be worried about retaking it and sticking with your academic plan. If not, take the D as a lesson and move on. OP, you didn't specifically say you got below a 2.5 gpa, is this actually the case? If your CGPA is above a 2.5 AND your TGPA is above a 2.5 despite the D, then you have nothing to worry about except trying to do better next time. You won't get kicked out for a D, trust me. You get kicked out for failing to comply with standards. If you meet the standards, you're good.
