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.

We have two kinds of crash courses: BASIC and REVISION.

BASIC CRASH COURSE – for beginners or students who have been out of touch with science practicals. Features: slower pace of teaching, more teacher demonstrations and hand-holding. Focus is on how to set up the apparatus, using instruments correctly, recording, tabling and graphing.

PREDICTIVE REVISION CRASH COURSE – for students who need a refresher course or guided extra practice for science practicals, such as retakers, government school students or graduates of our Basic Crash Course. Features:  Quick recap on how to use instruments correctly, and what examiners look for in students’ recordings, tables and graphs. More discussions on sources of error, important or predicted topics, difficult experiments and Planning (if applicable).

For details on Practical Courses, Mock Exams or Schedules, kindly click on any of the above links relevant to the exam and level you will be doing.


Why Us?

  • Our teachers are highly qualified and very experienced, and we actually TEACH you good practical techniques.

  • We have been a one-stop comprehensive science practical centre providing solid practical training for ALL THREE sciences and for all levels and streams since 2017.

  • Our laboratory apparatus are exam-grade and the same as those used in MOE schools and our chemicals are all NEA-approved.

  • We have a structured practical training programme catering to the needs of both beginners and experienced students.

  • We have a small class size so that the teacher is able to observe the actions of each student more closely and demonstrate the correct practical techniques where and when necessary.


You may need science practical lessons if you are a private candidate who needs a science lab and apparatus as well as practical coaching, or you are a school candidate who needs more practical training to get top grades.


IMPORTANT INFORMATION FOR PRIVATE CANDIDATES 

The registration for ‘A’ and ‘O’ Level exams as a private candidate usually opens around early to mid-April (Please check SEAB website). If you are registering for a Science subject (Physics, Chemistry, Biology or Combined Sciences), at the time of registration in April, you will be asked whether you have done any science practical training in any school, centre, or institute. 

Thus if you are considering Singapore Learner as your science practical training provider, you are strongly advised to register with us and begin your science practical sessions for each subject BEFORE APRIL for us to certify that you have attended basic science practical training. Thus it is recommended that you commence practical training with us in Jan/Feb. Please note students usually do about 10 practical sessions per subject to be competent in practicals.


The following is taken from SEAB website:

“If you are registering for a Science subject with a practical paper, you:
• Must have sat the same Science subject(s) previously, OR
• are currently attending or will be attending a course of instruction in Science practical at any institute/school. You must complete the course of instruction in Science practical at the institute/school enrolled in. You are required to declare that you have fulfilled the above requirements at the point of registration. Registration for the subject may be cancelled without a refund of the examination fees if a false declaration is made.

b) Using Effective Strategies to enhance the understanding of the key historical developments, changes, challenges and impact (outcomes) on Singapore’s growth:-
**The “Prince James Approach” to consolidate conceptual understanding
**the 5W + 1H strategy to grasp relevant details and boost mastery learning

MODULE 2: Applying the Studying skills

a) Understanding the core SBQ Skills: simplifying and structuring the “I.C.U.R.E” skills
b) Developing SEQ skills – Using the PEEL strategy to write effective paragraphs
c) Developing Annotational skills
d) Mind-Mapping skills
e) Use of Mnemonics
f) Understanding the LORMS
g) Time-Management Skills

MODULE 3: ASSESSMENT MODES

**Formative and Summative Modes

  • Quizzes
  • Short- Answer Questions
  • SBQ
  • SEQ
  • Research-based Questions on Key Historical Personalities and Events
  • Time-Lines
  • Oral Presentations

SCHEDULE : Every Thursday 30th Nov – 21st Dec
