The academic content is in Arabic, as at the BAC and as in the app.
What the syllabus expects from you
- Deriving nouns/adjectives from verbs with suffixes: -ic, -ty, -able, -ment, -y, -ing
- Forming opposites with prefixes de-/dis-
- Basic spelling rules when adding a suffix
The method
- Identify the root, then test which suffix category (noun/adj/verb) the sentence needs
The common mistakes
- Wrong suffix category (using a noun suffix where an adjective is needed)
- dis- vs de- misuse
