Wow, the difference really seems big. According to the system you described, I just passed my A-levels and will be going to uni in a few months.
In India we don't have the credits system and instead of grades we get marks/points(exams of 40,70, 100 marks). Academics here focuses more on theory rather than practicals. We don't have many projects or presentations( I don't have a problem with this since I have severe social anxiety disorder and prefer not to be the centre of attention
) but thoery exams are more important.
And also schooling system here seems to be rather simple than what you described. Grades 1-5 are called Primary, 6-10 are called secondary, 11 and 12 are reffered as senior secondary. After we pass Grade 10, we allowed to choose different subjects based on our score in grade 10. There's Science, Commerce and Arts streams. Science stream is further divided into PCMC(Phy, Chem, Maths, Computers) and PCMB(Phy, Chem, Maths, Biology). I opted for PCMC.
The commerce and arts are considered for less "intelligent" students, not by the students though it's mostly a belief of parents and teachers(yes).
The increase in difficulty and change in subject matter is substantial in Grade XI for science students, many who used to score 90+ in grade X have now difficulty in passing, this sadly leads to suicides of many students due to very high expectations from the parents.
For the next 2 years we learn the subjects we chose and the mandatory English subject. The scores we get in grade XII is stamped on everything we do next. I plan to do B.E in Computer Science.
I hope I am not bothering you, but would you consider listing some of the stuff you learn in subjects like Phy, Chem, Maths in grade XI-XII, just want to check that what we learn here is similar or not.
Thanks for taking your time to write this.
