More about Barriers 

The second paragraph presently begins: Study tech attempts to remove what it calls "barriers to study".  Study Tech defines 3 barriers.  As a dictionary defines words and as biology defines the cell "nucleus" and the "cell membrane", well, Study Tech defines 3 barriers which it says exist.  It says, "there are three barriers to study", that is its message.  It spells out the barriers and it says how to deal with these barriers when a student encounters them.  Could we have Study tech defines three barriers to study and purports a methodology of dealing with them? The reason the present sentence is not accurate is because no matter how many times a student removes a barrier, he may meet the same barrier in the next word he reads.  A student educates himself and then deals with barriers when he meets them.
