This would then result in it all not adding up to 1? @roshankarms462 Says: Jeez, i think this is the first 10 minute video ive ever seen from Freesciencelessons @karishmaharris Says: I love your videos! You are single handedly saving all of us!! I appreciate you so much @crl_midladder Says: Are your A level videos for OCR, AQA or Edexcel ?
