Which sittings are examined?

AKU-EB examines the syllabus in both the Annual and the September sessions.

How is Paper II marked?

Paper II is 35 marks: 21 for constructed responses and 14 for extended responses, each either/or. Marks follow the exam-specification table by topic.

Is the practical marked on the platform?

No. Paper III is a separate practical exam with a journal, held at the school.

Is this official AKU-EB marking?

No. Aga Khan University Examination Board marks the real exam. This is examiner-style marking of mocks and homework for AKU-EB HSSC Biology. Only you see the marking, and you decide what reaches the student.

Do you reproduce past-paper questions?

No. Every XI–XII paper here is original and written to the biology hssc syllabus 2025, in the same structure as the real papers shown above.

Which papers are marked?

None yet are marked question by question; Paper I are scored instantly. Practical exams sat at the centre are not marked here.

How is the next paper chosen?

From the marks a student lost: the concepts behind them are ranked by marks dropped, and the new paper weights those topics. It is the same syllabus and structure, with new questions.

AKU-EB HSSC Biology: where the marks go

AKU-EB HSSC Biology is a 100-mark qualification sat at the end of each class: Paper I is 50 compulsory MCQs on an OMR sheet, Paper II is 35 marks (21 for constructed responses and 14 for extended responses, each either/or) and Paper III is a 15-mark practical held separately. Papers I and II share a three-hour sitting. The syllabus fixes the marks topic by topic, and the cognitive weighting is Remember 0 to 15%, Understand 45 to 60% and Apply 25 to 40%. Marks are won on the exact term, a reason attached to each described process and labelled diagrams, so loose wording is the usual leak.

AdmitPortfolio builds Biology papers to that table, with applied MCQs of the kind seen in the model paper and extended responses that ask for explanation with diagrams. Paper I scores automatically; Paper II is marked question by question as each rubric is released, with the exact term and the reason behind each lost mark named.

How each paper is marked here

Paper I (50 MCQs) is scored automatically and reported by topic against the syllabus table.
Constructed responses are marked for the exact term or step asked for; extended responses for completeness, reasoning and labelled diagrams.
Practical marks come from the school’s practical exam and journal and are outside the written marking.

Where AKU-EB HSSC Biology candidates lose marks

Describing where an explanation is asked — Describe and explain are different tasks. A process listed without the reason it happens loses the reasoning mark.
Diagrams without labels, or labels that miss the part — Unlabelled diagrams cost marks in extended answers, and a label line must touch the structure it names.
Terms used interchangeably — Diffusion for osmosis, breathing for respiration, gene for allele: in biology the exact word is frequently the mark.
Data and scenario items answered from memory — Stem-and-data questions reward reading the information given. Recalled textbook facts tend to land on the distractor written for them.
Either/or extended answers that run across both options — Each extended response is either/or. Writing half of each leaves neither complete and leaves the examiner with nothing full to credit.
