## Stack Testers Revision Friend Description
Stack Testers Revision Friend is the latest addition to the suite of apps developed by the Engineers of CES Environmental Instruments, one of the UKs leading environmental Test Houses. The app has been developed as a revision aid to UK Stack Testers in their preparation for the Environment Agency’s MCERTS examinations.

The app provides an ever ready reference source for all the current Level 1, Level 2, TE1, TE2, TE3 & TE4 examinations. The revision is in the form of multiple choice questions that can be selected for each examination and scored into 20 question tests. Test results are stored within the app and can be reviewed in the analytic section by a comprehensive progress chart showing the subject areas that need development.

The Useful Documents section contains information of the documents needed for examination revision and links to the up to date Method Implementation Documents (MIDs) and Technical Guidance Notes (TGNs) published by the Environment Agency.

There are links to web sites providing additional revision information and a helpful image gallery.
