Attached is the solution i made to the sample task released by OCR, it has been created using Python (version 3) with the use of the SQLite3 library. An SQL database was created called students to store the information needed. The program allows the user to log in and do the following: 1. Enter and store the students details 2. Recall a students details (need ID number) 3. Show all students 4. Show students by gender 5. Show students by form 6. Delete a Student 7. Log out the data in the database was created using a random name/street generator.

Attached is a lesson on how to create a login system using a csv file in Python. Included are the following: 1. PPT explaining how to create a login system 2. Example programs (in zip file)

A simple resource to teach the students about sequencing and flow charts at KS3, it includes all the terminology needed as well as the correct way to develop a flow chart using the correct symbols. Also included is a task related to the use of a "Big Trak" which was used to programme a sequence of instructions. I used this for 2 lessons to get the students used to the ideas of flow charts and sequencing prior to programming. **If Big Traks are unavailable you can also switch this task to something like Flowol as the resource will have already given insight into flow charts
