As a CEC student you have free access to the Grammar App from Guided E-Learning.
This App is an in-depth grammar reference that also lets you practise using the language with interactive sentence building, activities and exercises.
If you are trying to improve your English, this App lets you target the specific grammar areas that are difficult for you. You can focus on what you are studying in class, or review language you have already learned.
Preparing for a Cambridge or IELTS exam? Use the App to get quick access to hundreds of exercises that will help you improve more quickly.
You can use the App on the bus, or while standing in a queue!
See the links below for more information.
Remember, the App is free to download and you can log in using the same username and password that you use for CEC Online E-learning.
