The IP allows students to skip the O-level at secondary four and be admitted directly to junior colleges (while there are cases of students being asked by the school to "leave" this system as their pace could not be kept up). However, the students would still have to take the Mother Tongue O-level. All the schools allowed in the scheme accepts the top 10% of the national cohort. This ensures that students who are under the IP are able to cope with their A-level after bypassing their O-level.
