Hello,

Yes, of course you can appear for December Term End Exam as you said you have already submitted your 2nd year assignment which is compulsory for appearing in TEE, so in case you have some problems for appearing in June TEE which is to commence from next months onwards, you can without any worry fill in the exam form of December TEE, the reason being you have taken admission in 2019 though you haven't mentioned in which session, but your admission remains valid till 2023 January/June (as per the session in which you have taken admission)

since you have already submitted the assignments, so you're already done with this one, usually prior to the pandemic, the exam form for December TEE used to come out by September but as you must be aware due to covid the entire academic schedule is changes, so whenever the form is released, you just need to fill in by providing your details for the papers you will be appearing, and other essential information along with paying the exam fee in online mode through net banking/credit card/debit card, that's it. there is no such elaborative process to mention here, in case you still have any doubts you can mention in the comment box below.
