Next my 24 month window opens for 11B at the time theres no seats for the school. Also my GT score is 88. And also im an E-4 prior service? Will that effect me from relcassing to 11B?

As of right now, there are no class seats for 11B, so you'll either have to wait until a seat becomes available or you can pick another Priority MOS.

As for your 88 GT Score ... you'll need to check your CO score.

(1) A physical demands rating of very heavy.
(2) A physical profile of 111221.
(3) Color discrimination of red/green.
(4) Correctable vision of 20/20 in one eye; 20/100 in other eye.
(5) Qualifying scores.
