You may get admission in BCA, but it is better to repeat theory paper. It will be helpful for your future because in BCA course include mathematic in its 2 semester which is of 12th level for 1st and 2nd years in the first semester the level is basic then the level rise as per the syllabus and as the next semester begins.so you need to keep practicing maths along with BCA to get any job.
You can also do polytechnic if you Pass your 10th board exam with a minimum of 50% marks in Mathematics, Science, and English.

Hello Aspirant,
Yes, you can definitely cope up both the arenas if you keep in mind that time management and consistency are the key. Afterall, this is the very way to success.
Being a final year B.Tech student, balancing your MERN stack coaching along with GATE 2025 Preparations can be challenging in real, but I want to share some tips to help you manage both:
- Create a realistic schedule where you must prioritize your Gate Preparations since it's a crucial exam. Set aside specific 1 hour for MERN stack coaching as you have decided yourself.
- TIME BLOCKING : Divide your day into blocks for different activities (coaching, Gate, self study, breaks). Don't do Multitasking in between coaching and Gate Topics within the same hour.
- Utilize your weekends , here you can revise your MERN stack concepts and some part of the time for intensive Gate preparation.
- Solve GATE-related problems regularly .
- GATE MOCK TESTS : This is important for your self assessment. Analyze your results in it.
- Stay Healthy
