Hello,

You can submit your BCA assignments of first semester at your study centre, you can do so by visiting the college in person or by post, whatever seem convenient to you, actually after pandemic IGNOU has commenced this process of online assignment submission which is extremely beneficial in the sense you just need to upload your scanned assignment copies in google drive through a link that's usually provided in the official website of RC, now there are many RCs as well who don't follow this procedure, if you visit the official website of RC Kolkata the online link for assignment submission for Dec TEE is available but the same is not for RC Patna which has online submission only for June TEE and that's closed obviously, check out at http://rcpatna.ignou.ac.in/

hence you  have to visit your study centre personally or do so by courier service such as registered post/speed post etc, I would say if it's possible then visit in person your designated study centre, and there you can submit it, and get your slip mentioning the course, enrollment number, date of submission etc, signed by HOD, this will act as a proof of submission, in case if in future any misplacement happens you can show this to confirm your submission status. you can also visit our page at https://university.careers360.com/articles/ignou-assignment-status to know more details regarding this.
