You must see the content of the course 1st, duration, cost , infra, earlier students outputs and skill developed , in-time course completion record , certification process & delivery of certificate in time etc.
Also Same Brand has different centers and branches. Unfortunately all does not perform the same . Some centers are doing great some not, it varies place to place centers to centers and also on the local management & team.
So its always good to visit the institute personally, speak to them, see the track record and then decide if its up to the mark as per your requirement.
One more point i want to request you to keep in mind , see if there is any suitable institute in your accessible location which are not a branch or center of any chain . In single brunch/direct institutes normally have a good difference in their course precises , compare to the one which runs on franchise model , because normally all the franchises has to pay around 10 to 30% or above of their collection to the Franchiser accordingly the price is set, but in individual/direct institutes they normally keep the fees around 10 to 30% cheaper and mostly gives better service also.
