My kids are also going to Lyceum, they are still in primary. about 40k term fees. Studies are ok-ish, nothing to complain so far.
If they want to do medicine then I will tell them to do local O/Ls, A/Ls since we can choose in grade 9.
If you are comparing government and international, I do not have a clear answer but it seems like international schools teach a lot in primary than in government.
I went to a top government school but I do not like to send my kids to that since I do not like that half backed culture, and simply showing off and things on OB. And also if coping western culture we have to copy the original.
And this amount of fees is affordable to me. (not too high, not too low, either)
