Teaching Chemistry and general science

Hope everyone's doing great.
Hi this is Umna, I have a Master's degree in Applied Chemistry and been tutoring for the past 3 years. Looking forward to enroll in a MPhil degree Program as well. However, I am Experienced in Chemistry & General Sciences. Usually I am using a very simple format, as my content I've been using power point presentations, video lectures and for students query I took audio calls once in a week with my students.
Moreover, for the test part, after my every lecture we (Students & I) play a rapid fire questioning session. It makes them remember what they learned so far in every single lecture. Apart from this I take monthly tests and bi-weekly quizzes.
Well this is my way of teaching and still working to provide better content to my students for much more understanding.
As far for my subject chemistry & general sciences, I've been covering the books of all Upper secondary for of class 6,7,8 & IGCSE Chemistry of O'levels & Industrial chemistry related topics.
My areas of topics would be: Nature of matter, Experimental techniques, Atoms, Elements, Compounds (Related Problems), Stoichiometry, Electrochemistry, Periodic Table, Equilibrium, Chemical kinetics, Acids-Bases, Inorganic / Organic / Analytical Chemistry covering HPLC, GC, Thin layer Chromatography, Spectroscopy, Plane Chromatography & Ion exchange Resins, Environmental Chemistry, Industrial Pollution, IUPAC, Basic Industries of Sugar, cement, glass, textiles, Chlor-Alkali, Metallurgy, Nuclear, Sulfur dioxide, Food Industries.
For any query I am just a click away. Looking forward to it.
Thank you.
