how can i use student version instead of trail version

i was using student version normaly because i i use my university e-mail but by wrong i choose to use trail version and now i want to end the trail version i use student version again so what can i do

I have never used the trial version myself, but I expect it is simply a license type. If that is the case, you should be able to go to the license manager and log in to load your student license.

If that is too difficult, you can always reinstall with the correct license information.

You might also consider using interpunction, capitalization, and whitespace. It helps communication.

Delete all of the current license files; see https://www.mathworks.com/matlabcentral/answers/99147-where-can-i-find-matlab-license-files#answer_108494 for the location of license files.
