so there is no free student licence for sketchup pro?
No - it’s a nominal yearly fee, which I believe could be applied to the purchase of a full license in the future. SU Make is free.
The Student license is an annual, expiring license which you can read more about here: SketchUp Partners | SketchUp
SketchUp Make is free for non-commercial use and could be used for most Educational purposes, excepting the Pro Only features which may be necessary in some design curriculum.
Unfortunately your annual payment for a Student license does not contribute towards a discounted price later. That program was retired a while back.
