I am hoping to getting into B.Applied Finance and B.Actuary Studies at Macquarie University, Australia's oldest Actuary program, in order for me to get into the program I must get a HD (High Distinction = 85% or better) in Math135, which is very hard for me, so right now I am taking taking a easier math unit Math130, which should prepare me for the more challenging Math135. I must get HD in Math135 and I only have one chance, if I get a Distinction (75% -84%), I will out on the double degree. (May be I can retake Math135 again, but I don't want to waste time and money.) Macquarie does provide lecture notes for their various Maths units here, but they are old notes, disorganised, and have a lot of assumed knowledge. I wonder if there is a textbook out there I should study that will ensure I get a HD in Math135. Thanks.
