Could you please give me an estimate about how many hours it needs to be ready for the test? You would help me very much to program my time.
Thanks for your recent e-mail. Depending on your technical knowledge and background, and whether or not you can arrange to attend commercial classroom CCNA training or a "boot camp," it can take anywhere from two weeks to six months to prepare for the CCNA. Given your current workload of 90 hours a week, I'd suggest taking a slow and deliberate approach to the topic, and plan on spending 8-10 hours a week for 16-20 weeks to prepare for this exam. You may be able to find a local community college that offers CCNA prep classes, which typically require 3-4.5 hours per week in the classroom (3 hours lecture, 1.5 hours lab) for very reasonable prices. Such classes usually take 12-15 weeks to complete, which fits nicely with the schedule I've suggested. I also urge you to obtain the latest printing of the Cisco Press Study Guide for exam 640-607, which does an excellent job of covering the subject matter (likewise, the Todd Lammle 640-607 Study Guide from Sybex also gets extremely good reviews). An additional practice test is also a good idea to help you prepare.
