Winter intake is a good and safer choice as We don’t know when the pandemic will end. so fall intake might be not possible in this case.
If you want to study online then you can opt for fall intake otherwise jan intake is there. You can defer your course
Honestly it's really expensive for international students just taking courses online...
I need to choose between winter or fall 2021 intake... like wt u said, the pandemic, and also my aim.. (at least complete the diploma before age 27/28)
next year I will be age 26

As u may know, Seneca allows the deferral once only, so it's hard decision to me.
