<<@jeffchan9092 says : Hi sir, I am confused about how to interpret the kymograph because as you say when the subject inhale, the volume of the spirometer will decrease so wouldn't be the curve will go downward and the inspiratory reserve volume would show by a curve that goes downward? I understand the definition but I just get confused by how to interpret the direction of the curve.>> <<@tsunami_art says : Hi Sir, Thank you for making your videos, they are extremely helpful in revision. I'm sure you get asked this a lot but I wanted to ask how much of the A level biology and chemistry courses you have left to cover and which units they are? Also, do you think you will finish before this year's A level papers or is that seeming unlikely? Thanks again for all your work, its extremely appreciated!>> <<@abid430 says : hi, when will a level chemistry year 2 videos be done?>> <<@anakin_skywalker17 says : Hi Dr, I have your GCSE workbooks and I was wondering how would you reccomend using them - should i do one video then answer the questions on that video or do a whole topic then answer the questions? Also I would really appreciate if you could offer some advice. By the end of March we sre having tier setting exams for the sciences. It will be on the following topics Biology - Homeostasis, Inheritance variation and evolution Chemistry - All of paper 2 Physics - Forces And Space Im really stuck on what to revise. Should i revise only these for March and then start paper one in April or do paper one simultaneously. Any advice would be greatly appreciated.
