**There is also a summary of the course review at the very bottom.** I tried to create a routine of studying once a day, but the missions are released at 12:00 PM instead of 12:00 AM, and they don't last for 24 hours. This means they can only be completed within a 12-hour window. Since I tend to work late and get things done in the early morning, I wanted to establish a routine of taking lectures at dawn. However, taking a lecture at dawn and then having to perform the mission at lunch ruined my planned routine, forcing me to switch my study time to lunch... Naturally, there are times when that's not possible due to work. When I tried to rush through it late at night, I found that I was forced to sit and watch the lecture for at least 30 minutes, which once again ruined my plan of keeping a light daily routine. (There were cases where a lecture module ended at 25 or 26 minutes; in these instances, I was forced to play the next lecture for an extra 5 minutes and often ended up having to restart that next lecture from 0 minutes the following day.) Since the 30-minute requirement is mandatory and it's difficult to take classes at my desired time, the missions given—at a point where studying was already difficult—were things like installing an app or setting up notifications... When I asked if a refund was possible for the reasons above, I was told that these kinds of missions only exist on the first day and not later on. So I tried to keep going, but the missions that followed were things like writing acrostic poems based on what I learned. I ended up spending more time on that than on actual studying, so there was no benefit at all, and I just voluntarily dropped out; The OT (Orientation) felt like a waste of time as it was more of a social gathering than a place for sharing necessary information. It wasn't pleasant to see some questions being ignored or scrolled past, while the focus remained on chatting with people they already knew. I think it would have been more appropriate to at least say, "Please submit a separate inquiry for questions that are difficult to answer on the spot." ====================== Review Summary: Personally, it was very disappointing. I wouldn't recommend this to those who want to create a study routine and focus solely on studying. (Strange situations often occur where the routine is flipped or consumed by missions + the verification process is more tedious if it's not an Inflearn lecture). If you just want to casually have fun, write acrostic poems, and build a habit of recording things, it might be worth considering.
