I know, only the first part of my post was your answer haha

sorry!
First of all, EB is taken by students who go to the European schools (most of their parents work for the EU), while the IB is mostly taken by students who go to International School.
The IB is marked out of a max grade of 45, while the EB is marked as a percentage of 100. For the IB, each subject is marked out of a grade 1-7, and then you can get up to 3 extra points for the combined grades of your TOK Essay and Extended Essay.
75-80% of an IB:ers final science/humanities/math/arts grade is from the exam taken in May, and 20-25% is from an Internal assesment (project) while for languages the exam taken in May is worth 50% and the orals and written internal assessments are worth 50%. For EB:ers, their grading works like this:
15% coursework from 7th year (last year of EB)
25% exams in January
24% Oral exams in June
36% Written exams in June
For the IB you take 6 subjects, plus write a 4000 word Extended Essay and a 1500 word TOK (its like philosophy) essay. For the EB you take 11 subjects.
Both the EB and the IB comprise of many compulsory subjects.
The EB comprises of the following compulsory subjects: a foreign language, a science, mathematics, philosophy, gym, history and geography (these are taught in the students' first foreign language, i.e. English, German or French).
The IB comprises of the following compulsory subjects: at least 1 foreign language, English, at least 1 science, at least 1 humanities subject (geography, history, ITGS, B&M, Economics, Philosophy or Phsycology), and math. Optional subjects include art, theatre and music. In total you need to have 6 subjects.
For the IB we have to take at least 3 subjects at Higher Level (HL) and 3 subjects at Standard Level (SL). The higher level subjects are usually graded harder have more exams because if you study a subject at a higher level you are expected to have further knowledge of the subject than if you were at standard level. There are therefore more teaching hours for a HL subject than a SL subject.
ok a long post sorry

but hope you have further understanding of what the difference between the two are now
