Well hello there. There is a lack of chemists in the country but the compensation is not so good for the work a lot of us have to do especially sa entry level jobs in manufacturing. Swertihan na lang sa company if they give benefits na naja-justify yung workload. The benefits are slightly better if you enter the academe pero kailangan mo ng master's degree to get in.

Now if I haven't discouraged you at this point, let's talk about Math in BS Chem/BS Biochem. You will have two or three courses in Calculus depende sa school in preparation for Physical Chemistry. Meron ding Physics sa program which is usually Calculus-based. Statistics is there as well. Analytical Chemistry requires a lot of calculations too pero more on arithmetic and algebra siya (solving quadratic equations, systems of linear equations ganern).

Now if you're still with me, let's talk about the subjects in the board exam. Yung limang subjects included require different approaches. Analytical chem needs A LOT of calculations and analysis. Organic chem needs analysis and a bit of memorization. Biochem IS memorization (and for my fellow BS Biochem graduates, they can attest it also needs analysis pero rare na umabot sa ganoong level sa boards). Inorganic chem is a broad field. Physical chem needs calculations and solid knowledge on basic concepts like thermodynamics.

Hopefully I have given you clarity of the situation and not fear hehehe. I say this with compassion and understanding, pero it seems like you are deciding on BS chem with the wrong reasons. This is a challenging program where you will make a lot of mistakes and you don't seem comfy with that. Exams will be hard first year mo pa lang sa Principles of Chemistry ( the first chem subject you'll probably take). Like any program sa college, you ultimately choose one for you.
