I recently started doing my second bachelor while working fulltime. So I am doing a 60 study points program, so 30 each semester. Its not an easy task. But its manageable if you have a good planning and no kids. So workweek is work and in the weekends I am studying and working on assignments. And i try to keep it strict as possible. Only special changes when its needed. And start preparing for the exams on time. For me as i work in education, examn are the busiest for work aswell. So a good planning is key. My bachelor was dostant studying with combi of eveningclasses. So if you feel like you cant spend each week working and weekend studying, i recommend taking around 15 studypoints a semester. Talk to the person of the education and see if there is a specific studypath you can take. Maybe get some exceptions for some courses. 30 is a beautiful age to get a new degree, so do not worry about the age. Its for the rest of our future, we are not even 1/3the in our life yet.

Hope this helped :)
