About the Teaching Team
The Chemistry teaching team includes K. S. Tan (15+ years teaching IGCSE Chemistry), Ms Yash (10+ years teaching IGCSE Chemistry) and Ms Kartini (15+ years teaching IGCSE Chemistry). Lessons focus only on Cambridge IGCSE Chemistry 0620, for Year 10 and Year 11 students.
What the service is built around
These figures are across LearnWithRig tutoring as a whole, not Chemistry alone. More than 75% of students improved by at least one grade within one term when they attended consistently.
Past results describe previous students under the stated conditions. They are not a guarantee or prediction of any individual student's outcome.

1. Diagnose
The first job is to separate a content gap from a calculation, application, exam-language or practical-skills gap. The solution depends on which one it is.
2. Teach
Core and Extended students do not need identical content. Lessons are aligned to the student's papers, weak topics and examination timeline.
3. Apply
Worked questions, mark points, calculations and practical scenarios reveal whether the student can use the Chemistry rather than only recognise it in notes.
Founder and service lead
Rig is a Mechatronics Engineering graduate from Universiti Teknologi Malaysia and has 8 years of teaching experience in IGCSE and SPM Math and Add Math. He oversees the service, tutor matching and the learning system. He does not present himself as the Chemistry teacher: Chemistry lessons are taught by the Chemistry team.
His free Math teaching channel has more than 9,000 subscribers. That education background informs how the service is organised, while subject-specific Chemistry experience is stated separately and transparently above.
View LearnWithRig on YouTubeThe resource library is mapped to Cambridge IGCSE Chemistry 0620 (2026–2028). Technical pages distinguish Core from Supplement, link to relevant examination skills, and are updated when a syllabus or factual correction requires it.
Teacher experience, pricing, trial terms and student results are kept as separate facts. We do not imply that the founder's Math results are Chemistry results. Chemistry testimonials are published only with the reviewer's permission, and we do not publish grade or outcome claims without evidence.
The full source hierarchy, correction process and update policy are available in our editorial policy.
New students begin with a paid 1-hour lesson at the assigned tutor's hourly rate (RM80-90/hr). There is no package commitment after the trial.
Our Chemistry teaching team includes K. S. Tan (15+ years teaching IGCSE Chemistry), Ms Yash (10+ years teaching IGCSE Chemistry) and Ms Kartini (15+ years teaching IGCSE Chemistry). Students are matched according to their year, Core or Extended route, current level and timetable.
No. Rig is the founder and an IGCSE/SPM Math and Add Math educator. He oversees the service and tutor matching. Chemistry lessons are taught by the Chemistry teaching team.
The service supports both routes for Cambridge IGCSE Chemistry 0620. The lesson plan must distinguish Core content from Supplement content and prepare the student for the papers they are actually entered for.
Every new student begins with a paid 1-hour trial lesson at the assigned tutor's hourly rate. It is a real lesson, not a sales call, so the family can judge the teaching fit before continuing.
We publish Chemistry-specific proof on the results page as it becomes available. We do not relabel Math results as Chemistry results or invent student outcomes.
Share the student's year, Core or Extended route, current grade and weak topics. We will reply with the next suitable step and trial-lesson options.
