Hey guys,
so I know that I can get credits with my diploma, however some schools would put me in advanced standing courses and others would just give me credis, may one be able where the difference is?
If you are awarded credits, then a certain number of credits in that subject area will be listed on your transcript. Depending on the subject area and the material covered in your earlier program, you might be given credit for a specific course at that college/university. You will not need to take as many courses to graduate from that college or university as you would have without those credits.
If you are awarded advanced standing, you will be eligible to take higher level courses in that same subject. You will not have any credits recorded on your transcript and you will need to take the same number of credits to graduate as the rest of the students need to.
So why would one choose to participate in advanced standing? According to Princeton they somehow are eligible for accelerated graduation, but how?
Usually you don’t get to choose one or the other. Whether you get credit or just advanced standing depends on the individual institution’s policy.
I have no idea how things work at Princeton. You need to ask them how things work there.

FYI, one does not have to accept advanced standing. I worked to hard to get into the college of my choice; since I can financially afford to, there is no way I am leaving in less than 4 years. 
Having said that, this is the type of question that is better asked once one actually has received admission to a college.
Some colleges use the term “advanced standing” to refer to students who can choose to matriculate in sophomore status, rather than freshman status, due to a sufficient number of credits awarded for pre-college work. Those colleges would use the term “placement” to refer to the concept happymomof1 described: being placed in a higher-level class without necessarily getting credit for the courses you skipped. (Once you start college, you’ll also hear of “placement tests” for math or foreign languages - they are used to place students in the appropriate courses, but you would not normally get credits for the courses you skipped based on the result of a placement test alone.)
At private universities such as Princeton, most students would NOT choose to matriculate in advanced standing, since this would limit their ability to take full advantage of everything that Princeton has to offer and might put them at a disadvantage when applying to graduate school.
However, students usually accept the recommended course placements. Who wants to repeat material that they have already learned in high school? If you are ambitious enough to get accepted to a university like Princeton, you probably want to learn more.
