My story

I'm Ruchi — currently teaching the IB Diploma Programme in Chemistry (SL & HL) at Toronto French School, guiding students through the Internal Assessment and Extended Essay process every year. Before that, my classroom has spanned three countries: Chemistry and Physics at St. Stephen's School in Chandigarh, India; Chemistry at Al Khor International School in Qatar; and Chemistry across several schools here in Ontario, alongside SAT instruction and a stint as a Chemistry & Biology teacher at Queen's Elite Academy.

My foundation was built in India, where I completed my B.Sc. in Chemistry, M.Sc. in Organic Chemistry, and B.Ed. in Science before ever stepping into a classroom. After moving to Canada, I worked to earn my Ontario College of Teachers certification in Senior Chemistry — and I keep myself professionally current with how the IB curriculum evolves, year over year. I've also privately coached 7–10 students through SAT prep, every one of them landing a strong score.

Ru's Science Cafe grew out of a simple observation: the students who do best aren't the ones who memorize the most reactions — they're the ones who actually understand why a reaction happens. That's the whole philosophy behind every session I teach, whether that's a Grade 9 student just starting to build a foundation in chemistry, or a Grade 12 IB student finalizing an Extended Essay under deadline pressure.

My teaching philosophy

  • Diagnose before teaching. Every new student starts with a 30-minute diagnostic session — not a test, a conversation — to find out exactly which concepts are shaky underneath the topic they're stuck on.
  • Concepts before formulas. Equations are easy to memorize and easy to forget. I teach the reasoning first, so the formula becomes obvious rather than arbitrary.
  • Close the loop with parents. After every lesson, I send a short summary email — what we covered, the whiteboard notes, and what to review before the next session — to both the student and their parents.
  • Exam-literate, not just subject-literate. IB exams are external and marked strictly against command terms — "state," "explain," and "evaluate" all require different depths of answer, and precision matters as much as knowledge. I train students to answer exactly what's being asked, not just what they know about the topic, so they capture full marks rather than losing them to imprecise wording.
