Grammar Booster - Frequently Asked Questions (FAQs)

What is Grammar Booster?
Grammar Booster is a student-led, self-paced eLearning course developed by Native English Educators. Students interact with the content and receive immediate feedback throughout the course as they progress through the levels. A certificate will be auto-generated based on their score and can be downloaded and printed by the student. 
Interactive content has been calibrated to provide students the grammar skills necessary for their grade level and to set them ahead of the learning curve. 

What is the difference between Fun with Grammar Booster and Flying with Grammar Booster?
Grammar Booster has been designed to introduce and boost the grammatical knowledge for primary students of all ages. With this in mind, there are two courses to choose from. Both courses explore the same grammatical concepts but have been designed to suit learners of different ages. You therefore, only have to subscribe to one OR the other based on your child’s primary level.
Fun with Grammar Booster is recommended for students in Primary Levels 1-3. There are 20 levels, each taking approximately 20-30 minutes to complete. Each level introduces and builds upon ONE concept, allowing for younger primary students to internalise grammar in a much more focused way. The language and images cater to this age group so that they can understand easily and enjoy the learning process.
Flying with Grammar Booster, comprising 11 levels, is recommended for students in Primary Levels 4-6. Most levels explore more than one concept for composite learning that refreshes and boosts the grammatical knowledge older primary students will have already acquired. The more detailed language is suited for older primary students keeping in mind the pre-requisite knowledge, time required to complete each level and their attention spans.

I have two children in lower primary. Do I need to register both of them or can I subscribe and use it for both my children?
To track their individual progress and to earn individual Grammar Booster certificates at the end of the course, both children will need separate logins. We recommend subscribing one for each child so they can learn at their own pace and get certificates in their own name.
