The Activity Series and Solubility Rules are critical for the inorganic chemistry section of the exam. A student must look at the table to determine if Zinc can displace Copper from a solution, or if mixing Silver Nitrate and Sodium Chloride will result in a solid precipitate. Without the priedas, these questions would be a test of memory rather than scientific inquiry.
Despite its utility, the priedas is a source of many student errors. chemija vbe priedas

The Lithuanian model sits in the middle. It is more generous than the AP exam (which demands more memorization) but less generous than the IB (which provides spectral data). This reflects Lithuania’s focus on calculational rigor over spectral interpretation. The Lithuanian model sits in the middle
This is not just any periodic table. It is annotated specifically for the VBE.
