I am really confused about these two options between bsc in computer science from BHU ??? Or btech from bbau Lucknow (central university) Placement ke hisab se batana plss ?!!! choosing bsc over btech is it beneficial?? Kya bsc BHU me placement hoti hai yasc karna padega all together 6yrs?!!! Seniors studying there plss tell!!!

I am 2023-2027 batch student. I was allotted ME branch in a tier 2 central university engg college. I had plans to upgrade my branch to something else but I couldn't due to bad marks. Have been an average student till class 12th then took a drop for an year for college entrance but couldn't crack jee so went to univ college and since then have only downgraded. In the first year itself I got two backs due to personal health issues. In 3rd semester I passed all but in 4th sem I got three backs by 4 marks recently. I have already cleared one back from 1st year and now total i backlogs I have are 1 (M2) from 1st year and 3 from 4th semester. Now I am in 5th sem 3rd year and I can only give my remaining backlogs paper in even sem (6th or 8th) but it's gonna be hard probably to pass all in 6th sem as there going to be 9 subjects including 4 labs. Other than this, except my lab courses, every theory paper except a very few, i have really bad marks in theory papers mostly with D or C and overall CPI is 5 currently after all the backlogs (since marks don't count for backlog subjects at all) My problem are I'm really not good in my branch and jobs in mech are tough unless you have a really good academics history or knowledge of subject. I have concluded I'm not good in studies and at least not for engineering particularly for my said branch. I am just looking to complete the degree now without any gaps. My questions are is it possible to overcome this situation some way better? Like I'm going to try to clear as much as backlogs in 6th sem and trying to score little better in all 4 semesters from now but is there anything else I can do? Also, I know it's bad to ask this question after all, do I still have hope for placements? Particularly I might go into tech role jobs since some CS related companies take mech graduates too but with this performance, are there any chances? A lot of money (according to my financial limits) has been spent for the course and the outcome is like this all because of my mistakes.. I want to recover this for my parents now though as I had planned to get a job before joining btech so anyone of you if you have passed through such stage or could give advice for the same, I would be very thankful to you! P.S: you can all let me down so I realize my mistake even more but pls give some advice, I'm really depressed from a few days because of recent results.

Qualifications: 12 passed CBSE, 87.6% PCMB student. So I took admission in BTech+MTech dual degree biotechnology in KIIT. Now in India the scope of biotech is limited. I matched my CUET answer (not the final answer key I didn't check it yet) and got 589/750 in PCB. I was thinking if I can get into BHU in BSc Chemistry and then try for BTech CSE next year by practicing maths more, is that better? KIIT is taking possibly every student in CSE or CSE AI ML, that time I didn't know that or else I would have given KIITEE exam in PCM and not PCB.
