I highly recommend that you read through the articles prescribed prior to starting with the course. This will give you an idea of what to expect. Once you start, please try and work out a schedule for yourself and STICK TO IT!!!
Develop the habit of sticking to your planned time as well as possible. Discipline yourself and read as much as you can. Try to print articles so that you could read through them in places where you would not have access to your laptop/PC. I find reading on my cell phone a bit annoying. However, this could work for you.
I know you are a working individual, thus time is important. So I also suggest trying to dedicate 1 hour of the day to studies, whether it be morning, lunch time or night time, whichever works for you.
Try not to mix work and studies. You lose focus on both this way. Unless your employer is willing to give an hour per day at work. This, however, may vary if you are required to be on site/out of the office at times.
Regardless of the time, set an alarm for this.
Also, separate your studies from your family time. It will not work while the kids are awake.
Work through the course day by day and try your best to stick to your schedule. Create a schedule and tracking document for yourself which will serve as a dashboard to keep track of progress and what needs to be attended to.
I wish you all the best.
