If you have excellent knowledge of MS Excel and MS Access, you may wish to pursue the MCT, however there are some important considerations:
1. Do you have any desire to be in an environment where you are giving instruction to individuals from a wide scope of society (i.e. differences in work experience, background, education etc)?
2. Do you get frustrated trying to explain things to individuals with less knowledge than you?
These two questions are going to be very important in making an informed decision about the MCT program.
First, if you answered yes to the desire to become a trainer then that is half the battle. The second step is in seeing how others perceive your ability to teach/explain concepts to individuals with a different knowledge base and level of expertise.
There are ways to overcome frustration in the teaching environment,however your discomfort will be passed directly onto those you are teaching. It has the potential to make things uneasy and unproductive for both MCT and students.
I do suggest, if you haven't already done so, to take your MOUS certifications prior to enrolling in the MCT program.
