I've gotten an offer to take an MCSE CBT course w/ guarantee to pass. It's not just an exam prep, but full on training. They will give me the full package plus the A+ training for $1299.
I've seen the Transcender site,and it seems to be geared towards just passing the exams. The other one also has on line help and 1-800 number for specialists to answer questions. I know the transcender is about 1/2 price, but it seems as though it's a bit watered down, don't get all the modules you would need.
Any suggestions before I commit?
