You can also study vocabulary per topic. For instance, if you´re reading an article regarding gardening, highlight those words that are new to you, review them and later on do something related to the subject. You can watch gardening videos on youtube, and see if you recognise any words that you´ve just learnt. Afterwards, review the article you previously read before and, finally, try to speak to your teacher using gardening as the main topic so you can try to use the words that you have learnt. Do not overload yourself with too many words at once and give your brain some time between tasks.
Another idea is that you can put these words on the fridge so you see them often, and when you have learnt them, try to change them for new words.
Hope it helps!
