1. All the symbols in electricity, ac current and how it works, resistors

2. It was interesting to AC current

3. It was hard to understand

1. Learned about how batteries convert chemical energy into electrical energy, how do electrons create a potential difference, volatage and batteries uses in diagrams

2. It wasnt interesting

3. It was hard

1. Pages -: 347,348,349,350, learned about circuits of electricity, symbols used in igcse to describe every electric component

2. It was okay

3. It was hard

1. Lightning, logic of lightning, electricity and magnetism, alpha and beta particles, emf force and voltage

2. It was interesting

3. It was hard

3 questions covered, most about beta, alpha particles and electricity

Questions covered - 7,8,10

1. I understood that gravitons are particles that exert gravity, this is a theory to define what quantum gravity is, gravitons and how they create gravity, is quantum gravity real?

2. It was interesting to get a new perspective of gravity

3. It was hard

1. Pages -: 328,329,330. Learned about voltage and emf formulas in multiple cases, learned about resistance, its unit value and formula

2. It was interesting to know the similarity between emf and voltage

3. It was mostly easy cause i did a deep research on this before

1. Learned about reflection in mirror, Points of reflection and refraction, Volume, density calculation

2. It was interesting

3. It was hard

1. Nuclear decay, unstable nucleus, alpha decay, how are alpha particles produced and what are they, beta decay and how do they happen, role of gamma rays in radiation

2. It was interesting and more understandable, could relate more

3. It was hard but research paid off

1. Question covered, convex and concave lens, calculation of focal point and refraction of rays, focal length, principle axis, converging and concave lens, optic center

2. It wasnt that interesting but i understood the concept

3. It was hard and irritating to understand the logics

1. Plancks constant, what does it represent, relation to plancks energy formula, black body radiation, joules x seconds and waves/second relation

2. It was interesting to know how constants are used to define energy

3. It was extremely hard to understand the formula and relate the constant to real terms

1. Energy, work and power, formula relation, meaning of each concept, visualized these 3 concepts using real life examples, formula of kinetic and potential energy, how are 3 of them related

2. It was interesting, i understood the concept clear and got a sort of relevance of the concepts in real life

3. It wasnt hard as videos helped me out
