Let's say I'm taking a course which is 4-week long. Which is the right tense to use?
1. After attending this course for 2 weeks, I [found/ find] this course to be very informative and useful.
I think 'found' is the right choice but, on the other hand, 'find' sounds logical because the course is still on-going.
2. After attending this course for 2 weeks, I [have learned/ had learned/ learn] a lot.
