My study plan has basically just been to adopt what works and discard the rest. For those who know me, I am a huge fan of Bruce Lee and his philosophy for Jet Kun Do is similar. What worked for me was to basically focus on one topic for a week. Read the Chapter, review the material and ask any questions to a senior Networking Engineer or post a question in the community. Take a practice test on the material and go back and re-read anything that you missed.
The nice part about taking a class was the fact that our instructor made us read one chapter a week, and then review the material in class, do some labs related to the chapter and then take a weekly Quiz on the chapter that we just studied. This worked really well for me. I was able to absorb about 85 to 90% of the material each week which was reflected on my grades for the quizzes. When studying for the Network + or any other certification, I have adopted this strategy and we will see how this works at the end of the year when I take my exam.
