I have done the same thing before, but I even started a bit later than you. It's really not easy to remember the word especially when you tried to read newspaper, the words there are mostly difficult for secondary one student. So my recommedation is to read interesting english stories to learn more vocabulary first. It is because when the story is funny, you will be more likely to remember the word than just a news in a newspaper.
Second, after you dropped down the words, you have to take out your notesbook to read often. Not just the first few days.
Third, dont try to learn too much for one day, just 2 or 3 evey day would be more effective. Then when you catch up more, then you can increase the number of words you learn.
And lastly, when you have english writing assignements, try to read your notesbook of vocabulary once before you write and see if you can use them. You may find a amazing result.
