yeah, todd lamle is good for CCNA but not enough to get 85% n more in CCNA exam. They asked you pretty minor but notable question in CERT exam. you have to know troubleshooting for switch and router. If possible go with online matarials. if you have any friends in nepal they may help you to get downloaded version of CCNA netacad matarials (Be careful and dont show any american that matarials if you find any, otherwise you will violate copyright law and sued by cisco). But keep in mind to get CCNA you have to know each and every things in that matarial. good luck.
