Edit and correct grammar

I scored a 99 overall on inventory.  It really shows how I think method of learning should be. I think both of andragogy and pedagogy have positive side, so teachers need to find out the positive side in both thus combined them in one concept to be more effective method. I think even adults need a teacher to explain the materials. Even though, I think in some subjects such as Literature, and history, a teacher can use the andragogy methods, I see it is difficult in science subjects for instance.
