One way to improve your grammar

One good
way to review and improve your grammar is by following the grammar categories
in the following order:

1.  pronouns;

2.  determiners and quantifiers;

3.  possessives;

4.  adjectives;

5.  adverbials;

6.  verbs;

7.  nouns;

8.  clause, phrase and sentence.

Tip: you should practice by making your own sentences
on EACH category and sub-category; this is the best way to learn HOW to
properly write and speak in English.
