Universities understand the plight students are in during the pandemic, and most universities are moving towards blended learning with both physical and online classes so that no student is left out. However, the uncertainty of changing to full online classes remains, depending on the situation of the Covid-19 cases in that specific country.
Many students as well as lecturers were introduced to online learning during this pandemic. Tutorials, classes as well as meetings with lecturers are carried online, in addition to being able to access libraries only through digital resources.
While some students find this form of education not so effective, there are many students who find it more suitable for them than face-t0-face classes. For example, one of the biggest perks of online classes is that you can record the classes and watch them later at your own convenience. You can also join your classes anywhere, anytime.
The cons of online learning that have been pointed out by many students is that they are unable to get the real university experience such as making new friends, doing group work and extracurricular activities. Another major problem you might have if you are studying in a different country might be the time difference. If there is a big time difference between your country and the country you are pursuing your studies in, you might find yourself waking up in the middle of the night for a 10am class.
Hence the answer to the question of what it is like to study during a pandemic can be very subjective and you can only find out what it is really like for you once you start your studies.
