Didn't read it all, so sorry >< no disrespect to you, but i g2g!
First thing "I'm Fred, or Freddy" LMAO, ><
"Hello and welcome"
Ok, enough stupidity, Economics without Unit 1/2 is EASY, um, in my class we had 1/4 not do 1/2 (class of like 12), and basically 80% of Unit 3 >>IS<< Unit's 1 and 2.....its a revision of it.
Unit 4, merely USES what u learnt in Unit 3. Um, when I did 1/2 in year 11 and looked at the textbook in Jan holidays, it freaked me out for "economics" isn't taught in years 7-10 like other countries. HOWEVER, ignore the feeling that its hard! It is really hard to understand when u havent had a class yet or a teacher.
But trust me on this Economics 3/4 is EASY without 1/2. HOWEVR, if u muck about in semester 1 aka unit 3, yes, u will struggle unit 4.
Goodluck
btw sorry about talking about ur intro, but its so unique! I dont see that often >< as u can quickly tell im the immature one on VN at times, enjoy ur time here.
You will be pleased to know not everyone is like me ><
EDIT: Regarding Business Management, tbh i picked Economics over it because I never saw myself owning a business or learning how they run, and quiet frankly i didnt care ><, also the scaling down sort of "topped off" why i chose Economics over it. But thats just ME, i know others will tell u differently
