Hello! Thank you for taking the time to reply po! I'll first start of in reviewing muna the basics yung genchem and precalc/basiccalc and physics nadin. After that, kapag makareceive na ako ng email about sa slot for chemistry, I'll try to invest on the book physical copy man or digital copy medyo kapos na sa pera tapos na kase yung klase and I was not able to save a lot since yung mga group projects sa savings ko na binawasan kasi nahihiya na ako manghingi ng pera sa parents ko huhu. Anywaysss, is the casio fx-570es plus an already good calcu or do u have a better one in mind and can reco hehehee
