I will summarize some points that I didn't like:
1) Episode 1 was fairly decent, but there was a scene where Nac and Pang are sent to Ladda's office and Pom and Ladda just keep watching them as they beat each other up and I found that so disturbing that they turned on each other so quickly. I mean, weren't they friends once? It's almost like their friendship meant nothing anymore.
In Episode 1, their potentials also get "awakened" by presumably hearing Ladda (at least I thought it was her) over the speakers, but why is it they were capable of hearing it when they didn't even know how to manipulate the potentials? The same applies to seeing the numbers during the presentation. Unless Wave somehow manifested his powers during that time, it wasn't really explained.
2) Episode 5 was pretty intense, but there was also a scene where he literally almost killed Korn despite Wave starting the fight and everyone was just watching them. He even smashed one chair on him and people just kept watching. All the teachers and students... He was literally killing him and the only one who stopped him was Claire after like a whole minute. That was the beginning of decline for me and I started losing interest.
3) Episode 6 was Mon's episode. Mon was a very interesting character but there were too many things wrong with this episode. First, why did the pheromones manifest only in this episode? She'd been a part of that club for so long and they must have gotten in contact with her sweat before. I will not comment on the zombie makeup or their behaviour or the zombie acting, but it was quite bad. The fight scenes were also disappointing, but the relationships with the other club members were quite nice. At the end, there was another stupid thing. It's been months and Pang still hasn't even realized what his gift is (no idea how though), so he commands Nac to smash his head against the wall and Nac does it against a railing and Pang just watches in disbelief as his friend repetitively smashes his head against the railing and doesn't even bother to stop him and just watches. At that point, I was so done with this series.
4) Episode 7 was Korn's episode. I quite liked Korn before this episode, but they completely ruined him this episode. He was so sweet in Claire's episode, so I was very curious about his potential. The whole mess with the cloud thing and being held hostage with a simple knife was a bit too much. We didn't even find out the full scope of his potential.
5) Episode 9 and 10 were Wave's episodes. I was quite disturbed by the student-teacher romance because Wave was like 14 at the time. What really bothered me with episode 10 was how easily he created so much chaos in the school. People behaved like wild animals. Namtaan was probably the only one with the brain because she left the note as she left the roof. Wave blamed everyone but himself that he was naive and did that teacher's master thesis for her! Then magically they stopped him as he was about to unleash the files (even though Pang said there never were any? but it didn't seem like it at the time) through power of friendship? Somehow Punn overhacked him? That was so stupid. Wave was supposed to be the computer master.
6) Approximately 5 months went by since the awakening, but Pang and Korn still had no idea what their potentials were?
7) The whole plot of episodes 9-10 could be resolved if Pang just used his power on Wave and made him stop since he actively used his power in episode 8 and 7.
8) In episode 11 Pang used his power to nearly kill Tamtaan, he kept pushing her and pushing her even though he knew she had a blood pressure condition. Pang and Wave started putting their silly plan into motion.
9) In episode 12, they had to gather the pins from other rooms. So in this episode, it was like they didn't even spend 6 months together. They all kept attacking each other because of the condition that the one that didn't have the pin would be kicked out, but they didn't even realize that since they are so precious, they would never do that. I absolutely hated that Pang and Wave didn't inform Ohm and Namtaan about their plan. So in the end, somehow Pang managed to outsmart Pom and he made him remember all his memories, but... what really bothered me was how easily Chanon sacrificed himself for Pom. He had the gift of seeing the future. He could have planned out everything.
10) Episode 13 was kinda interesting with the ending, but it was so weird that their school's new hack-proof system was better than Wave? Also where was this system when Wave literally hacked the school in episodes 9-10? Also at the end, when the director asked the students if they would give up their gifts in exchange for them being ordinary, Wave didn't say anything? I mean, what was even his plan? Did he just want to crush the system while keeping his abilities? Also Mon and Korn magically appeared like nothing, so they were back and they also didn't want to give up their gifts? But they allegedly gave them up 2 episodes ago, so they definitely wanted to get rid of them.
11) It was cool they used a lot of English for written stuff, but did they really expect Thai students to be so fluent?
12) Why did the director need government funding? He could have just brought along Pom, made someone rich sponsor them and Pom would erase their memories. They could have groomed a small army this way.
13) The twins didn't even have their episode and somehow weren't even present for the evaluation or other stuff?
14) The whole conflict could have been solved easily had Pom just erased the director's memory and then Pang could have manipulated him as he saw fit.
