关于Newcastle纽卡斯尔大学的口笔译专业
我刚刚去官网上查，发现它的入学门槛有两种：
Stage 1 entry
An upper-second-class Honours degree or a degree with a minimum average of 75 per cent (or GPA 2.75) on your transcript. In addition, we require native English speaking applicants to have good degree-level knowledge of Chinese. When applying, please enclose any evidence you may have to support your second language proficiency qualification. We will also consider applicants on an individual basis with lower or non-standard qualifications who have at least two years' full-time experience as a translator or an interpreter.
Applicants whose first language is not English require IELTS 7.0, with a minimum of 6.5 in speaking and writing and 6.0 in listening and reading, which must be no more than two years old on starting the programme. No equivalent English language qualifications can be considered on this programme.
Stage 2 entry (advanced)
An upper-second-class Honours degree or a degree with a minimum average of 80 per cent (or GPA 3.0) on your transcript. You must also have expert second-language knowledge.
Applicants whose first language is not English require IELTS 7.5 with a minimum of 7.0 in all sub-sections, which must be no more than two years old on starting the programme. No equivalent English language qualifications can be considered on this programme.
The UK Border Agency (UKBA) has rules for international students regarding minimum English language requirements.
求问第二个进阶的和第一个有什么差别？好像都还是需要读两年。
