You’ll have to master the math concepts whatever physics class you take anyways. Not a big fan of algebra physics because calculus based gives a gives a deeper first principles understanding, you can literally see how everything is related. Typically students take 4 years of science in high school, if you spend 3 years on physics there’s less time for Chemistry, Biology, Computer Science and some additional math like Statistics or Multivariable. Even if you use some electives, and skip introductory classes you have make some tradeoffs. Not to mention humanities, social sciences and foreign languages. Most importantly you need to avoid getting Bs because you got in over your head and can’t keep up. |
Yes, exactly. Kids need to master algebra-based physics before moving to calculus-based one. However, algebra based physics should be started in middle school. Here are the kinds of problems DC did in seventh grade: 1. A lift of mass M is acted upon by force F, causing the lift to move upward. A weight of mass m is suspended from the lift's ceiling using an inextensible thread. Determine the lift's acceleration. If the thread breaks, what will be the accelerations of the weight and the lift relative to the ground immediately after the thread breaks? The mass of the thread is negligible. 2. A glass cup in the shape of a cuboid has a square base with sides a = 4 cm and height h = 6 cm. The thickness of the vertical wall is d1 = 0.4 cm, and the bottom thickness is d2 = 0.8 cm. What pressure does the cup exert on the surface when standing normally, and what pressure when it's turned upside down? (Glass density is ρ = 2400 kg/m³) 3. The cheetah is the fastest land animal. The maximum speed a cheetah can reach is vmax = 112 km/h, which it can maintain for a maximum time of tmax = 20 s. Our cheetah covers a distance of length x. For the first t1 = 180 s, it runs at one-seventh of its maximum speed, then runs one kilometer at one-quarter of its maximum speed, and runs the remaining distance at maximum speed. Since it got a bit tired before reaching maximum speed, the time during which it runs at maximum speed equals half of the longest possible duration of the cheetah's running at maximum speed. Find the cheetah's average speed over the entire path. How much time would it take the cheetah to cover distance x if it runs at one-eighth of its maximum speed the entire time? Consider the speeds on each individual section to be constant. |
In America, ok? In many countries students have all the sciences every year. But you think you must have the exact same classes every day. |
AP exams are post-tests, so they aren't helpful as pre-tests assessing readiness for enrollment. MCPS creates this problem by forcing double-period AP sciences, just to make time for occasional labs. AP does NOT recommend every day double-period. AP recommends a 104-to-125 day x 45minute pace, https://apcentral.collegeboard.org/media/pdf/ap-biology-course-at-a-glance_0.pdf https://apcentral.collegeboard.org/media/pdf/ap-biology-course-and-exam-description.pdf "Flexible or modular scheduling may be implemented in order to meet the time requirements identified in the course outline for lab and field experiences. You may find that at minimum, one double period a week is needed to allow adequate time for authentic lab experiences" Other schools do things like mixing PE into the double-period, instead of MCPS absurdity of having 1 of 4 years be the "PE every day year" |
Then I suggest you send the kid back to that mythical country and to that wonderful middle school that teaches university classes. By the time they finish high school they’ll blow everyone out of the water and be ready to receive their well deserved Harvard admission. Unless in that country they also one up the American system and do graduate level classes in undergrad like medical school. Or do medical school and residency there too, right? You are a little obtuse, people are trying to give you advise not debate what educational system is the best. |
LOL |
This is way easier than AP Physics 1. Have you looked at the free response questions for AP Physics 1 - they are very abstract and confusing. There is a reason AP Physics 1 has the lowest AP pass rate. Some 9th graders can handle it just fine but most cannot |

First of all, I never asked you about advice, and in fact, I resent your patronizing tone. You don't know more about this than I do. Second, I didn't see anyone saying middle school should be teaching university level classes, ok? Middle schools around the world are teaching actual intro science classes so that their students can take AP level-like classes (and above) in HS. American middle school curriculum is complete garbage when it comes to science. It's a total waste of time. Then, HS picks up the slack but students run out of time to pursue more advanced classes, or they can only do so in one subject. To go back to the topic, this is why students and parents are inquiring about skipping intro classes. They are trying to compensate for the time their kids lost while fiddling fingers in their science classes, year after year. It's a real problem, and experience in other countries shows that 1) it can be done i.e. it doesn't take once in a generation genius 2) where the problem is (middle school). |
Is this for you or your child? What grade, and what courses do they want to take? There are ways to bypass the requirements but it depends what you’re trying to do. Are you trying to take Physics 1 in 9th and the high school requires honors physics as a prerequisite? Then show you don’t need to take the prerequisite. Talk to the department head, ask for alternatives. Offer to take the honors physics exam, take an online class that covers the material and get a certificate of completion to show the school. If that doesn’t work check the local community college for summer class that satisfy the prerequisite. They might still not allow it but if you’ll be courteous and persistent it might work. Going in with the mindset that the American educational system and MCPS are stupid and somewhere overseas you’d get what you want is the opposite of what you should do. Be reasonable with what you want. Are you planning for AP Physics, Chemistry, biology and Calculus the same year? That’s completely idiotic. From now till August there’s time to work something up. Start by looking at course placement policies and figure out how to meet the spirit and letter. |
My child took AP Bio (without a prerequisite) in 11th grade at Blair. The class wasn't a double-period so it went fast. Some kids did struggle. |
Ok so this is for your child not for you. The school doesn’t care that in your head you think it’s done somewhere in the world. They care about placing students appropriately in the class. If not, they risk having the class filled with dummies with pushy parents that will drag the class down because they don’t even grasp the basics of pH when they teach Lewis bases and acids. So they can’t keep the pace of the class because they need to go back to explaining simple things that should have been mastered in and out. In the end it’s the top students that suffer the most because now they get a watered down AP class that might drag down their AP scores and their college prospects. Hopefully you can see the point of view of the school, it’s not because the American middle school curriculum is garbage. |
If you paid attention to my posts you would have realized that I do understand the point of view of the HS. By the time kids get there, the damage is done. But high school wouldn't be in this position if middle school science curriculum were not grossly deficient. Students should have mastered basics of Ph, Lewis formulas, be comfortable translating physics problems into equations etc in middle school and they should be able to jump straight into AP chemistry, AP biology without introductory classes. Introductory science classes belong in middle school. It is not a coincidence that this is what HS parents and students are trying to skip. |
So are you here to vent to looking for advice on how to skip? Is the student in middle school and you want them to skip middle school curriculum and take the high school prerequisites of AP? Is the student in high school having taken the middle school curriculum and now wants to take AP directly? What grade and what classes? Have you talked to the school and they won’t budge? You need to be more specific about what problem you’re facing. More important, how do you know the student is prepared for the class you want them to take? How advanced are they in other areas? Is the workload easy for them in their current grade? Because if they struggle in math and English it’s hard to ask for skipping classes and frankly not advisable. |
Reach out to your school and ask them. Thats how I always do it. You are going to get very varying advice here, some hostile. |
