Exam technique

Plan how you will allocate time (wisely) Use “reading time” to check your understanding Also to plan time allocation to questions Plan the order of answering questions

Answer everything (get the “easy marks”) Even if you don’t know the answer, show that you have some

relevant knowledge

Write clearly and efficiently Start with outline/bullet points, then expand if you have time No need for fancy style, full sentences Handwriting needs to be easy to read!

If you need more space, use blank pages but leave a forwarding pointer in the provided space (where the marker will be looking)

Illness

If you are unwell, and it seems that you won't be able to demonstrate your knowledge/skill properly, then you can request special consideration

Follow the same procedure as during semester (get medical person to fill out special USyd form, hand it in within one week)

Usual outcome: an alternate test, a few weeks later If you become sick during the exam itself, raise hand and

speak to the invigilator The University goal is to get a fair assessment of what you

have achieved

Pragmatic Advice

Find the room location before the exam day itself! Come in plenty of time (don’t rely on public transport running

smoothly on the day of the exam) Bring spare pens Bring water Have your student id and put it on the desk Be relax

The exam will not be a surprise It will examine the content of the course, with emphasis similar to

lectures, labs, and assignments

Project Summary

Project implementation All groups chose MongoDB + Neo4j

Data Modelling MongoDB

Most groups have two collections, with slight different document content Key issue:

• Where to store the listening count and tag data?

Neo4j Most groups have two nodes and various relationships Key issue:

• Store tag as node or relationship?

Combined Schema Most groups have structural data stored in Neo4j and property data in MongoDB Key issue:

• Where to store “tag” data?
