Maybe you wanna try American Degree Program (ADP).

Most colleges offer it, but they don't really transfer you to top tier universities because most of the credits you get here would not be taken.

Not really. ADP is a course which transfer your credits to the university of your choice, to cover your credit there for the first year, and maybe the second year, and maybe even part of the third year(only very few universities would do so).

And, for all the US universities, you would have to take up what they call as general studies. That means, you almost study everything during your first year. You may need to take up a music subject even though you're and engineering student who has really no connection to music(i presume).

So, you can actually think of any kinds of course you wanna major in, architecture, archaelogy, to zoology. The only problem is the number of credits transferable. Let's see, if you wanna major in some really unpopular subjects in Malaysia like forensic studies, environmental studies, etc., the number of credits transferable would be less than those popular majors such as business, engineering, etc. because most ADP providers would not offer subjects which are transferable for your unpopular majors.

After all, you can still take up any course you want by going for ADP. It's just that your choice of universities is kinda limited.

I thought that those Americans don't know what CGPA is. They call it just GPA.

CGPA, probably, is used in Malaysia, correct me if I'm wrong.
