At Red Treen Infotech, we donât believe in using tricks to crack the test. We focus on a skill-based approach that leads to mastery. Our teaching philosophy is based on three key elements â concept, application and strategy. Red Treen Infotech's Counselors design a study plan for each student based on his or her strengths and weaknesses. The classes are overviews meant to introduce patrons to computers, the Internet, and various computer programs plus the other clerk and SSC classes.
