Recommended way to learn Chinese

I moved to Beijing for work. I joined Mandarin Zone more than a year ago as an absolute beginner for some part time course. When I had to adjust my schedule due to my work I got offered to move to another small group which were about the same level as me but follow another more suitable schedule for me. I really appreciated this flexibility. Both teachers I experienced there so far were nice and effective. Last but not least also the location is super central and convenient.
