Something to add to "Tipps and Tricks", I would think...







Going by what may be PC, it is possible to raise stats and do all the events. However, the iOS/Android may just be running more difficultly.
One problem I notice is that you probably should be sleeping more. I'd recommend at least sleeping in on Mon-Wed-Fri, as well as at least one weekend morning. If your energy is above 75% (it may be 80%), it allows the afternoon activities to get a bonus which, in the long run, can add up. Now, you may have to put some afternoon study in, especially if you are romancing someone which require grades (like Max romancing Anne)
Something else is if the energy gets to low, then your tiredness can lower the amount of points you gain as well.
Well the iOS/Android difficulty is set a bit differently, so maybe will tweak that if even in Easy mode is hard to get the endings. Anyway if by Spring Break you're at 190+304 = 494 surely you should manage to get the remaining 106 points by end of the semester??






@Lady-NeonHearts: Possibly you did not keep the energy up. No matter how the events fall, you will be able to get some stat up at least. But the amount of stat you get depends on the energy you have, so keep it above 80 all the time and you should be fine.
I think there was a bug in mobile with some characters difficulty, I fixed the Android versions, but for iOS will take more time!
