Praiseworthy Ngwenya

I hold a BSc in Applied Biology and Biochemistry (NUST) and currently work as a research scientist. Before that I worked as a laboratory technician. That means I don’t just teach biology from a textbook, I use it in practice, and I can show you why each topic matters.

What I teach
A-level Biology (OCR and other boards), IGCSE/O-level Biology, and introductory biochemistry and molecular biology.

What my lessons are like

Clear and step by step. I break each topic into small parts and build up to the full picture, so nothing feels overwhelming.
Core content first. I follow textbook or syllabus and make sure every key point is covered.
Active learning. You won’t just listen. I ask questions, use diagrams and real-life examples, and we work through exam-style questions together.
Exam skills. I show you how to read command words, structure your answers and pick up the marks examiners look for.
Your pace. If something doesn’t click, we slow down and try another way of explaining it.
