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?
Only commit if you have talked with techs who have used the course & passed. I am personally familiar with the following (and my ratings):
Test Out! (7 out of 10)
SmartCertify (7 out of 10)
Transcender (8 out of 10)
Sybex (6 out of 10)
Ask the folks @ this (and other) sites their opinion of the material out there. Also require that they send you a demo before you spend anything. If they don't have a demo, they must not trust their material.
Remember that the person you are talking to is a salesman working on commission reading from a scriptbook. It's you money & your future. Spend them wisely.
