There will be an opportunity for students to participate in a Q&A session at the end of the presentation.

Past paper check list

I have updated this and I will give you a paper copy on Tuesday. Use it with traffic light stickers/high lighters, to record your progress. The Section 2 questions have not been broken down in part or the spreadsheet would have gotten out of hand. However, feel free to create one yourself and post me a copy 🙂

I have also posted the sample question paper and the Section 1, 2 & 3 PDFs in the past papers page (at top of page). There are no marking schemes on the blog so you will need to look elsewhere for the answers.

Arrays

An array is a data structure that can store a number of pieces of data of the same type. While a normal variable can only store one piece of data at a time an array can store more than one.

Array need to be setup before they are used in VB, you also need to specify the size of the array in advance. i.e. DIM LastName(10) as String would create a ten item array of type String.
