I would recommend Commsupport to anyone looking to advance in their career path. Before attending Commsupport lessons I had difficulties in understanding and practical application of IT networking concepts. After attending the Commsupport CCNA and CCNP courses I started seeing the big picture of IT networking by enjoying the clear logic and beauty in planning, configuration and troubleshooting of complex technological implementations. The quality of Commsupport courses is outstanding. The teaching approach is based on explaining complex things through simple analogies, definitions and real world examples.
