How the School-Based Assessment is organised and weighted, the four skills assessed, the investigative project, and how Paper 032 replaces the SBA for private candidates.
5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
One mark in five comes from Paper 3, and it rewards what you do with your own hands in the laboratory.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Copy these into your notebook in your own words — that is how they stick.
SBA marked by the teacher and moderated by CXC; 130 raw → 40; 20%.
Private candidates; 2 h 10 min; three questions; 40 marks; 20%.
MM 30; ORR 30; PD 30; AI 40 (raw).
12 over two years: Year 1 = 60 marks, Year 2 = 70 marks.
At least 16; must include the seven required.
Experimental Skills 30; Use of Knowledge 10 (of 40).
Proposal 10 + implementation 20; may be done in groups.
Only the investigation marks can be transferred across Biology, Chemistry and Physics.
8 items modelled on real CSEC Paper 1 questions. Choose one answer for each, then check. Aim for 80% or better. Work each item on paper first.
Write full answers, then reveal the mark scheme and tick the points you earned (16 marks in total). Show all your working — method marks count. Your answers are saved on this device.
