What do teachers say about this resource? (6063)

This has been a really useful resource to help our students to revise topics. The presentations that accompany the worksheets are a great way for students to learn or revise topics independently, and the worksheets allow them to put this into practice so they can really focus on the specific areas that they need to improve on. It provides some really good exercises that help to build on students’ knowledge in a specific area and help to develop a more rounded understanding of the links between topics... The combination of the presentations and worksheets is a great tool for differentiation as there is plenty that the students can work through at their own pace, and there is a lot of support if they need it... The main focus is on the topics that are tricky to make resources for. The combination of having presentation slides and worksheets makes it a very effective resources that is flexible enough to fit into our schemes of work very effectively... The A Level technical topics provide a varied and detailed set of teaching resources and student activities. Without any modifications at all they are great for independent learning, and are flexible enough to work into a variety of schemes of works... The resource matches the specification very effectively. There is a really good breakdown of the topics that are covered and these cover the depth and breadth that is required.

Very detailed and super easy to follow... It covers some of the more challenging topics in detail which helps non-specialists deliver topics... Great resource if you are just starting out or shifting from teaching ICT... I mainly use it as a revision resource to support with activities I create. The activities match up with some of the other resources I have purchased from ZigZag... A good match to the specification

High quality and succinct, lots of options for delivery due to the provision of paper, PDF, PPT and HTML formats... It is structured, therefore can be used out of the box but can also be broken up to deliver in a different order.
