No. To expand on what Choppy wrote above, the issue of BS/BA depends on the particular school. I don't know what the practice is for non-US countries, but in the US there are three possibilities that I'm aware of:
(1) Many liberal arts colleges grant only a BA, regardless of what the major is (e.g., physics or art history). This does not imply that a BA in physics is somehow less rigorous than a BS in physics. I served as an industry mentor to an undergrad at Wellesley and another at Carleton. Both are elite liberal arts colleges with strong undergrad programs in physics. BA shows up on their diplomas.
(2) At many universities, you get a BS or a BA, depending on the major. E.g., a BS for science and engineering, and a BA for humanities.
(3) And then there are some universities that offer a BS or a BA in physics. Here a BS is more rigorous than a BA. E.g., a BS might require more advanced physics courses, a senior term paper, or a real senior research thesis. In other schools, instead of a BA/BS distinction, there is a BS/BS Honors distinction. For (1) and (2), you have no choice between a BA or a BS. For (3), you want the more rigorous program.
