... no it isn't. Junior cert is taken after three years of secondary school; unless you're telling me you did calculus at the age of fifteen, there is no way it is on the same level as the A-levels. Based on my own experiences with the Irish educational system (which were limited to primary school; my sister, however, did two years of secondary school) there is no way even the Leaving Cert is harder than the A-levels, except possibly in that it consists of six rather than three subjects.
Sorry, I confused GCSEs with A-levels.
I'd still say the Leaving Cert is harder than the A-levels though, six is the minimum amount of subjects you can do, most schools do seven
minimum and I'm going to be doing at least nine (my school does seven minimum but for various academic and personal reasons, I'm going to be putting on at least two extra subjects, if not more).
And this isn't including the Leaving Cert Vocational Programme (aka LCVP aka Links) which is another subject on top of all the others.
Then you must bear in mind that at higher level, English, Irish, Maths (the three mandatory subjects), Technology, Spanish, Italian, Japanese, Music and Tech Graph all have two papers, that Irish, French, German, Russian and Spanish have an aural exam separate from other papers of the exams, that all but Russian also have an oral exam, that Home Ec, Technology, Engineering, Music and Construction Studies have a practical exam, Art has three, all of the practical subjects require projects as well as a portfolio and each of the sciences (Physics, Chemistry, Biology, Applied Maths and Ag. Science) and Links also requires a portfolio. And both Irish and English requiring studying multiple poets and their poetry, a novel and two plays.
Each normal paper is about two and a half hours long, each aural paper about forty minutes, which means the average student (following the typical "English, Irish, Maths, <insert science here>, <insert language here>, <insert art here>, <insert practical/business subject here>" formula) sits about 27 hours in written papers alone, plus an hour in orals and three hours minimum in practicals, if not more.
Then after all that work, they only mark you on your best six.
Now, admittedly, my only knowledge of the A-levels comes from my British cousins, but when my cousin Jake (Irish) and my cousin Barney (British) were talking about the two of them, Barney seemed almost horrified at the amount of work Jake had to do with English, Irish, Maths, Physics (science), French (language), History (art) and Economics (business subject).
