for thinking I can go full-time study with two days of internship?

[CoolToned]

Actually it's an internship. Is this doable, without the "study" part getting hurt?

The four subjects are Python programming, and three Information Systems subjects.

Normally, students just have one other subject when they do internship. But this internship is not credited (although a very good opportunity for me) and I really want to graduate on time.

Surely that's no different to full time working with 2 days studying which plenty of people manage

Well it completely depends on how hard the course is, how good you are, and maybe how good a mark you want.
