I joined here for CCNA R/S training here a month back and it was the worst classes I attended in any institute. The trainers are not competent enough and some important topics like VPN which you will be using once you become a network engineer and which is part of the CCNA R/S syllabus are not taught as well. Sure, they will teach most of the topics in labs, but you will be blank theory-wise. Moreover, from today, CCNA syllabus will be updated to 200-125, and I don't believe Spectrum will update the syllabi in the near future.
On the bright side, you will get hands-on experience on some Cisco routers and switches, and hence a two star. My advice will be to join here only if you haven't ever felt any Cisco routers and switches in your life. Otherwise, you can self-study or take any paid online courses which teaches you using GNS3 and/or Cisco Packet Tracer.
