So what topics are most likely to be tested THIS YEAR?
Sign up for our Revision Crash Course for O-Level Biology Practical, details of which can be found here: O-LEVEL PURE BIOLOGY HANDS-ON PRACTICAL CRASH COURSE. Hurry, places are very limited as our lab can only take in 7 students max.
DO YOU KNOW THAT THE SCIENCE PRACTICAL IS WEIGHTED TO BETWEEN 15% TO 20% OF YOUR TOTAL SCIENCE EXAM MARKS?
It can actually make a 1 to 3 grade difference in your total points for your exam! And it is easier to score a Distinction for your Science exam if you are very competent in your Science Practicals.
Right now, ARE YOU CONFIDENT that you can complete your science practical exam and answer all its questions correctly in the time allocated?
If you are looking for SCIENCE PRACTICAL TRAINING, CRASH COURSE OR MOCK EXAM PRACTICE (FOR PHYSICS, CHEMISTRY, BIOLOGY), don’t hesitate to contact us at 65694897 or 88765498.
Singapore Learner has been a One-Stop Comprehensive Science Practical Training provider since 2017.
As at 19 Apr 2026, we have trained about 1060 students for their science practical exams and we have conducted a total of about 4044 lab sessions.
Our laboratory apparatus are exam-grade and similar to those used in MOE schools and our chemicals are all NEA-approved.
Notes on Sources of Error in O-Level Biology Practicals
We provide A-Level / H2 / IP and O-Level Physics, Chemistry, Biology and Combined Science (Physics/Chemistry/Biology) Practical Training/Crash Course/Mock Exams for both local (eg. H2, Singapore-Cambridge) and international exams (CIE, Pearson Edexcel, IGCSE).
