I joined in at Karrox to sharpen my skills at Linux operating system. All said and done, it was pretty much worth it. I had been looking out for institutes with a good reputation for training and most of my friends refered me to Karrox. I think these guys are pretty much excellent at what they do.
My training program was quite hands-on ( to be honest I was a bit apprehensive in the the beginning because I was not sure whether training institutes do offer such level of close-to-real-life training.) Our trainers were quite friendly and approachable; and pretty much patient too.
If you go to the biggies in IT training, all you get is lip-service and your often bundled into a training factory. While Karrox is pretty big, they have managed to retain the personal touch! I liked that the most.
The training material was pretty handy too. The best part is that they do stick to the text material guidelines while teaching. so one can always go back and recollect and pace up well in case, he has lost track ;) The lab and facilities etc. were good too.
I can only add that these guys are definitely worth considering before you make any decision on joining a training program for IT.
Cheers
