Do not send a video as a compressed file using rar. I cannot open it. At least send it as a zipped file instead. You can create a video, save it and share the link. Your university OneDrive has a lot of space, sharing the link would make it easier, if the video is too large to upload.

Sure, let me try again to upload the zipped file.

Ruyan,

I was able to watch it.

language can indeed be a problem. try to join clubs and societies to meet new people. This will help you much more.

Talking to friends and discussing with other students is very good because it can help you learn more. Remember that demonstrators and tutors are paid to help you in the labs, so it is important to also ask them for help.

Many people are also finding AF2 difficult. Glad to hear you already know how to solve the problems.

You got to know our typical weather. It's raining most of the time, and as it becomes darker every day, this can really be very depressing.

The rainbow was indeed very beautiful, and I am glad seeing it made your day.
