So really the only differences are the science and chemistry sections, do you think I should focus a lot on studying physics for version 5? And from everyones replys it seems like the online assessment is not really worth it? Is there anything on the 5th version that you feel like there was a lot of that I should devote more time to studying like ratios, percents, decimals.. oh and also is there spelling?! Thank youuuu whoever responds :)
