I learned that students in the ninth grade can take a ninth grade version of SHSAT to compete for limited admission seats that may become available in any of the specialized high schools.

Is the number of the available seats for each HS made public?
Regarding application process: do you apply to only a particular HS (ex. Brooklyn Tech and compete for the seats available at BT only) or is the same process as in 8th grade (meaning applying to all HSs and getting an offer based on score and # seats)

Any information that you can share about the 9th grade test it would be really useful. Mock exams, format, guidelines, websites, how did you prepare, etc

Thank you.
