I didn't have prior experience or knowledge with networking equipment and work full time. I don't have other IT certifications either. I initially planned to sit for the composite but the very first time I tried some practice questions online after reading an online ccna guide I got only 4/10 correct after spending nearly 1 hr on them. That was when I decided to take it in two parts.
Studied seriously for 4 months straight. Probably could have completed it earlier if I studied consistently both days during weekends, which I did only in the last month. Started with Lammle's book because Odom was difficult to understand but I moved to Odom once I picked up enough knowledge to understand him. In the end I found Odom more comprehensive than Lammle's, especially those chapters on troubleshooting Ethernet and IP routing. Those chapters are a must-read, no mattter how prepared you think you are from other sources. I also bought Chris Bryant's Udemy course, which I watched to understand some concepts I couldn't understand from both Lammle's and Odom's (such as the SNMA from IPV6). Despite Lammle's limitations, I remember he covers certain things Odom did not, such as how to identify broadcast storms from reading the "show int" output on a switch. I didn't use flash cards, but the way I forced myself to remember things was to occasionally open up Notepad on a computer and recall from memory all the topics, IOS commands as though I typing them in IOS without referencing anything. When I was done, I usually had about 10 pages worth of information. Those things which I forgot or misremembered I went through them again.
For labs I used mostly Packet Tracer, though the last 3 weeks I installed and used GNS3 to practice on some commands not found in PT, such as the NTP master commands
On the exam, have to agree with others here the language is really poorly phrased. I found myself asking multiple times, "Ok if this were correct, what would that imply about this other thing." or "This reads more correct than the other answer". For a few questions I spent considerable time deciding between the only two possible choices. There was a VLAN MCQ which I was stuck on for 10+ min. In the end I still don't know if I got it right lol. For the labs, I found that show run did not always work. Or that the "|" argument didn't work. But I didn't need that to solve the question. Never got a single subnetting question though, for those wondering. Finished in 1 hr 13 min.
The highest I scored on Boson's was 897 (last exam), 2nd highest 793 (3rd exam). Man, those exams are tough, partly because they test on material outside of ICND1 syllabus. I cannot recommend the exams enough but thought they may make you feel overwhelmed and underprepared for the real thing. For Boson my weakest topic was LAN switching but I guess it may be because they had some questions on VTP, STP and FIB tables which I had no idea how to do lol.
Now on to ICND2.
