Christian Castro is one of thousands of seniors in the city whose scores on the all-important Regents exams have not yet been tabulated.
"I feel very frustrated," says Castro, "It's also to my parents, because they're trying to plan a graduation party."
Unlike past Regents exams, this year's scoring relies heavily on computer technology and scanning.
"For a few days we have been waiting for exams to come in," said teacher Gregg Lundhal.
Lundhal and some 250 other teachers are hired to score the exams, but teachers are not allowed to score the exams of their own students.
Principals have been told that seniors whose scores are not yet recorded can participate in ceremonies but with no guarantees. Vanguard Principal William Klann says he expected test-scoring problems.
"You know, we had some questions about what the process was," adds Klann.
Cesar Olivera joined classmates in getting his cap and gown, but he does not know whether he passed his English Regents.
"It's hard, it's nerve wracking," says Olivera.
Efforts to catch up on the test scoring is set to continue into the weekend.
