Few grammar good practices

Even though you may find it a little boring, you must get a grammar book. Look for one that is easy for you to use.

Listen to and read English as much as you can.

You can create a word log, a special place to gather words that have the same function: verbs or action words, adjectives, adverbs, nouns and so on. Keep it with you always so you can add a new word whenever you are!
