Bachelor of Pure Mathematics with a minor in philosophy and Computer science elective

[ausernameisneeded]

Hi, I'm new to this forum.
I'm interested in an online bachelor of pure mathematics with a minor in philosophy (analitic philosophy) and with some upper level Computer Science classes and applied Math classes as electives.
I would like to do a master in mathematics (pure or applied or another one) at a top university,
I don't know which one yet but my choices will likely be from the top 100  QS World University Rankings.
Location: Central Africa
Your Age: 20
What kind of degree do you want?: It's in the post.
Current Regional Accredited Credits: 0
Current ACE, CLEP, or NCCRS Credits: 0

Any certifications or military experience? No
Budget: 10 to 15k max in scholarships (I don't have any money right now)
Commitments: I currently work full time.
Dedicated time to study: 15 to 25 hours per week.
Timeline: I would like to finish within 1-2 years
Tuition assistance/reimbursement: No
Right now I'm considering SNHU (even though it's applied math focused) for lack of better options. But I'm a bit worried about the quality of education there. I heard that courses are very easy  and unproctored.
Also for alternative credits transcripts, GPA and rigour matters.

Thanks for helping me.
