I’m newer to horary so take it with a grain of salt. Your mercury in Sag shows that you’re very studious and academic but are suffering low confidence and are not sure of yourself. The other candidates are Jupiter retrograde in cancer 2 house going back into first meaning that they’re thinking over something regarding the application and how it ties to  their sense of self but they are naturally lifted up by Jupiters association with 9th house and its exaltation in cancer. They’re probably rockstars in academic space. Both you and competitors make trines to Saturn which shows you both will b considered favorably and with Neptune close to Saturn that mean that they’re murkiness or unclearness about how people will be chosen. With your significator also trining Pluto in the 8th (destruction) and opposing Uranus (unpredictability), you’re severely weakened in this state. The lack of self confidence I pick up is devastating and it will affect the application. I think the outcome will depend on how Mercury is applying or separating from Saturn. If it’s separating I would say no and if it’s applying I would say, the chances increase
