Complete a grammar book
Any grammar book is fine. Personally, I recommend “English Grammar in Use” which is commonly used in many language schools. Also, if you are worried about your vocabulary, looking though one vocabulary book will not be a bad idea.
Read Aloud practice
Practice as much as you can. This will make you comfortable speaking in front of the computer.
Do one sample test
At the end of the first month, try one sample test. Target score is 35+ points overall.
Pearson Official Guide
Once you have completed grammar and vocabulary books, start working on the Official Guide provided by Pearson. There is lots of information in there but it is all valuable information. Read closely all the pages.
To improve your Read Aloud, start recording your voice and try to see if you can improve it.
