    Mlungisi Nkosi is literally saving my future at this point 😭👍🏼because I need to get good marks for my varsity acceptance, especially for physics. Thank you for being able to explain work in a manner we can all understand!. I've been watching you since Grade 10 and my understanding of physics has improved. Thank you ❤️

    Quick question,do they penalize us if we write CH3 instead of breaking it down???also when writing a structural formula,is there a specific side we should start on,like for instance maybe adding our alkynes and stuff??? because according to me its the same answer,but I need to know if there is a preferred starting point or either way is fine as long as the numbering is correct... I need to know this before I write tomorrow so please do respond. Thank you
