Uhm... today we started the new section, Periodic functions and also finished the Personal Finance. That is not the hard unit but we must be careful when read the question, and remember some formulae :
+GDSR
+PV of Loan ( when we lease a car)
+Equity of house
+Debt/Equity ratio
...I think that's it, ^^ Good luck to u guys and also good luck to me :P
