Yes, you might have a good chance of getting admission into a polytechnic with a score of 67% in your 12th HSC board exams.

The minimum eligibility for admission to a polytechnic diploma program typically varies between 50% and 60% marks in the 12th standard Science stream (Physics, Chemistry, and Mathematics) depending on the specific institute and program.

Since you have 67%, you meet the basic eligibility criteria in most cases.

Selection for polytechnic admissions often happens based on merit, meaning your score in the 12th standard exams is a crucial factor. Some polytechnics might conduct their own entrance exams for specific programs.
