我係2012 的alevel graduate
results 如下:
中化(as):D
UE(as):D
applied maths(as) : C

physics (al) :E

我25個choice 入面要求較低的科目:
1. UST 物流
2. UST mechanical engineering
3. BU statistics and operations research
4. BU BBA
5. CItyu Industrial engineering and engineering management
6. Cityu Managerial statistics

7.(HD) building technology and management (surveying)
8.(HD) Hotel management

我知我的results 都唔好...
想問問put 咩去band A&B 好...

另外...
我有選HKCC asso..
想問下讀完asso (assume 讀一年) + degree ,
total 係4 年定5年?
(i.e.因為 讀完asso 之後 照道理係升DSE 的degree...
咁係升DSE 的year 1 定year 2? )

十萬個多謝>_<!
