If you want to take SAT test 2018 with Essay (Essay is optional), the registration cost would be US $54.50. However, if you opt out of the Essay, your fee would be $43. For international students taking the test outside the US, an extra $49 is added to the registration fees. For SAT subject test, the basic registration fee is $26.

Good Luck!!!!
