Arrange timetable for each individual student based on their choice of subjects

Well, you can place lines like you want. For example line 1 Monday 1st hour. Line 2 Monday 2nd hour, ...
But i recommend to import the data into FET and place it with FET, since it can care about a lot of constraints, like max gaps per week, free days, min and max hours, ...
Especially if you do it for many years.

Actually, FET run many hours but it still has not finished yet haha

I guess you still allowed too many hours in StElTo, so it will be impossible in FET.
Please download the new StElTo version. I added in the hours tab a information that calculates the number of hours. You need to allow at least so many hours also in FET. It won't work if you set a lower number of hours in FET.
In normal case FET solves such a table in less then 1 second.
You can attach you latest file here or send me by email if you can't find the bug.
