Saturday, July 23
Went back tanglin for 5 hours of chemistry mentoring work. It was rather pleasant this time because there wasn't much questions asked from the sec 4s. Did some inspection on their practical around noon. They were dissolving Mg metal strips into HCL and H2SO4 acid. The instructions were simple but a quarter of them made different silly calculation mistakes... so noob man... could've been more conscious. 1 saturday sepnt just like this... shall attempt chinese essay later... I can do it !
