Farewell, for now...
Due to the remodelling of the the SAT in March 2016 and the resulting scarcity of good teaching resources, we advise prospective students to take the ACT. The College Board has only released seven official practice tests for the new SAT, while the ACT has over forty official tests which one can use to prepare well.
Note: It is a common myth that one must take the SAT. The ACT and the SAT are both accepted and equally regarded by all American universities.
