i'm taking a course right now during may-june semester, just now i checked the solar and the course i'm taking now doesn't appear on solar, but it does appear on my timetable. I did not drop the course.
help anyone?

you cannot see the courses on solar because all the dates to change/add/drop courses as past.
this also happens during the regular year if you have noticed, your term one courses are removed close to the new term as well.

nothing to worry about
