In 2018 and before, it used to be two separate subjects: Language (English) and Sciences (Biology, Chemistry, Physics, Math reasoning and Science reasoning). One needed to pass both the subjects to pass the test. From 2019 and onward the style have been changed. Now only science paper takes place with two sections:
Section A (Science Achievement Component) -- Biology, Chemistry, Physics. 20 questions per subject making total questions 60 in section A. There is negative marking of 0.25 in this section.
Section B (Cumulative Science and Math Reasoning Component) -- Math reasoning and science reasoning. 30 questions per subject making total question 60 in section B. There is no negative marking in this section.
Each year a threshold percentage for passing is made for each Section by taking the top 300 students in account. For 2020, Science Achievement Component had threshold of 70% and Cumulative Science and Math Reasoning Component had threshold of 74%. If one had more than 70% in Section AND more than 74% in Section B then he/she would have passed and shortlisted for interview.
