I cannot afford to take too many AP tests as they are very costly. I am not sure which tests I should take.
Will having a good score in algebra-based AP Physics 1 & 2 when I already have a good score in Electricity & Magnetism and Mechanics, cause any significant improvement in my application?
Do I need to take both Calculus AB and Calculus BC? If I had to choose between the two, which test would you recommend?

If you are on free lunch AP tests are free. If you are on reduced, they are $10 each. If you do not qualify then you most likely can afford them.
Don’t take both Calculus exams–if you can take BC, don’t bother with AB.
@RMNitMiTz I am an international student so I have to pay the full fees + the international fee irrespective of my financial status.
Are you a junior or are you a senior that has already applied?
I am not sure what junior and senior mean.
Junior means 11th grade, senior means 12th grade, as in final year of high school.
I wouldn’t think it’s necessary to take both physics exams and both calc exams.
One of each is fine. Colleges won’t prefer one over the other. However, if you are planning to major in math or physics, take the test that reflects your interests.

It doesn’t matter if you are an international student, every kid can qualify for free/reduced depending on their household income.
Why I asked is if you have already applied to colleges (you are a senior 12th grade) then the AP exams are only used to give you credits when you get to the college and won’t be used at all to evaluate your application because they are doing that now and test are in May.
If you are a junior - a student that won’t apply until this fall to begin college in the Fall of 2018, then having the AP test scores on your application can be a little bump if they are good, but they typically don’t hurt you if you don’t have them. They can be used to show proficiency in some subjects, but like @lindagaf said, don’t take two of same subject - that is a waste of money and time. If you are ready for BC take it, but if you are not and would do better on AB, take that.
Subject tests, AP scores, and grades in your classes can all represent how well you understand and have mastered material in a certain subject. In some cases (depends on school you are applying to and major) having more than one of those can be a differentiation, but you can only do what you can reasonably do and what is expected given your circumstances. So do what you can, but don’t stress what you can’t!
I spent 93$ for the December SAT subject tests (2400/2400 ^_^) exhausting all the money I had.
The AP India registration page asks for a fixed price of 143$ per AP test. It does not give any information about fee waivers.
If I am lucky enough, I can save enough money for one AP test before the deadline. I would also need to travel to my test center which is 200 miles away. That would cost another 25$ 
Will colleges accept GRE math? GRE includes UG level calculus, algebra and other interesting topics. It is costly but it is cheaper than 2 AP tests combined. I am homeschooled so I get all the time in this world to study whatever I want.I keep reading books which are outside high school syllabus and I am 24x7 online at stackexchange.com answering questions. I don’t think my online Q&A website profile is of any value.
What should I choose if I could take one test? Does the physics test have a bit of calculus?
@CADREAMIN I have applied for one college this year but I will be applying for more next year.
I made a dumb move by paying for the college app when the college actually gave away free fee waivers. I felt guilty to not to pay anything for the app.
Do not feel guilty for not paying for app! Use fee waivers whenever you can. Colleges make zillions on apps, they are helping you apply, use fee waivers whenever you can. You may be able to ask an admissions rep (look for international admissions advisor on the school website) if you can get a fee waiver to apply if it isn’t offered up front. Doesn’t hurt to ask.
Your questions about GRE math and homeschooling in the college app process are out of my wheelhouse,maybe some other posters will jump on here. There is an international forum, may want to post there as well, I am not familiar with that forum and how responsive it is, but can’t hurt to post there as well…
Ah, I thought you were in the US (where you can get free AP or reduced fee).
Honestly, don’t take Physics 1 and 2 exams! That’s a waste of money. You’ve already done Physics Electro Mag and Mechanics–that’s good! Those are the higher level Physics and the ones you’ll most likely receive credit for in college. Plus from what I know Physics 1 and 2 are more algebra based. By taking an exam for a lower level course, you are not going to impress anyone. IF anything, you would most likely score 5s on the exams because you know the material already…and if you don’t, it would hurt your application…so don’t take them.
Take the higher level course exams if you can-if you’ve covered the material, then take the harder one. In math, you get an AB subscore if you take the BC exam. So my advice: take the BC exam if you want to take an AP test.
You don’t need the lower level Physics exams or Calc AB when you can easily take Calculus BC.
If you find the BC topics difficult, then take the AB exam. You should be able to decide what you know by looking through past tests.
About GRE- I am also not certain. You will probably get more info on the international forum another person mentioned earlier.
I can take one AP test; which one should I choose? Calculus BC or Chemistry or Computer Science?
I believe that calculus has the highest value because it is a necessity for college courses irrespective of the major I choose.
I agree that taking a Calculus AP is better than a science, as getting a 4 or 5 in it will fulfill requirements for many programs you might end up in.
Agree, Calc if only one. Definitely not CS, that would be lowest priority of those.
If you are possibly planning to major in a science, math, or engineering program, between the calculus APs, I would recommend BC (you do get a subscore for AB in that exam, I believe). And of those three APs you are considering for cost consideration, the Calc BC exam has broader usefulness.
