Good point, but there are good reasons that many (public and private) institutions are reluctant to accept transfer credit in Physics from community colleges. Usually, public 4 year schools only accept CC transfer credit in Physics if the legislature (or other governmental authority) forces them to or if they can be convinced that a specific CC is doing a good job.
Of course, most four year schools will grant credit for a 4 or 5 on the appropriate AP Physics test. However, I have never seen a CC transfer student who would have a snowball's chance in hell of earning a 4 or 5 on the appropriate AP Physics test.

You might also have a look at my final exam (below) from an algebra-based physics course. Could you pass this final? If not, you'd have a hard time passing subsequent courses at most big state schools.
Many community colleges simply do not tolerate requiring this level of rigor to pass a physics course, because too many students fail due to poor work habits and inadaquate math backgrounds. Student complaints result in administrative pressure on the instructors to make the course easier to pass.

1. A 1500 kg car travels northward at 15 m/s, and a 3000 kg truck travels east at 10 m/s. The vehicles collide and stick together. What is the velocity of the cars immediately after the collision?
2. A stone thrown off a bridge 15 m over a river has an initial velocity of 15 m/s at an angle of 45 degrees above the horizontal. A) What is the range of the stone? B) At what velocity does the stone strike the water?
3. A 2.5 m long board has a mass of 30 kg and is supported on each ends by two vertical ropes. A 90 kg window washer stands 0.75 m from the left end of the board. What is the tension in each of the ropes?
4. A girl pushes a 35 kg lawn mower on a level surface with a force of 20N. The handle of the mower makes a 30 degree angle with the horizontal. A) What is the acceleration of the mower? B) What is the normal force exerted on the mower by the lawn?
5. A cylinder (I = ½ mR*R) starts at rest and rolls without slipping down a 25 degree inclined plane a distance of 20m. A) What is the velocity of the cylinder when it reaches the bottom? B) How much time did the cylinder take to reach the bottom? C) What was the acceleration of the center of mass of the cylinder?
6. A merry-go-round accelerating uniformly from rest achieves its operating speed of 2.5 rpm in five revolutions. What is the magnitude of its angular acceleration?
7. What is the pressure on an aluminum cylinder 10,000 m deep in water?
8. 100 ml of hot water at 100 deg C is added to a 0.1 kg aluminum cup containing a 0.03 kg steel spoon, both initially at 20 deg C. The water, cup, and spoon can be considered a closed system and reach an equilibrium temperature of 84.7 deg C. a) Compute the entropy change of the water. b) Compute the entropy change of the spoon. c) Compute the total entropy change of the closed system.
