ACT American College Test Information
		The ACT originally consisted of four tests: English, Mathematics, 
		Social Studies, and Natural Sciences. In 1989, however, the Social 
		Studies test was changed into a Reading section (which included a social 
		sciences subsection) and the Natural Sciences test was renamed the 
		Science Reasoning test, with more emphasis on problem-solving skills as 
		opposed to memorizing scientific facts.[12] In February 2005, an 
		optional Writing test was added to the ACT, mirroring changes to the SAT 
		that took place in March of the same year. In 2013, ACT announced that 
		students would be able to take the ACT by computer starting in the 
		spring of 2015; however, by the fall of 2017, computer-based ACT tests 
		were available only for school-day testing at limited school districts 
		in the US, with greater availability not expected until at least the 
		fall of 2018. 
		 
		The ACT has seen a gradual increase in the number of test takers since 
		its inception, and in 2011 the ACT surpassed the SAT for the first time 
		in total test takers; that year, 1,666,017 students took the ACT and 
		1,664,479 students took the SAT. All four-year colleges and universities 
		in the U.S. accept the ACT, but different institutions place different 
		emphases on standardized tests such as the ACT, compared to other 
		factors including class rank, GPA, and extracurricular activities. 
		 
		The main four sections are individually scored on a scale of 1–36, and a 
		composite score (the rounded whole number average of the four sections) 
		is provided.  
		The required portion of the ACT is divided into four multiple choice 
		subject tests: English, mathematics, reading, and science reasoning. 
		Subject test scores range from 1 to 36; all scores are integers. The 
		English, mathematics, and reading tests also have sub scores ranging 
		from 1 to 18 (the subject score is not the sum of the sub scores). In 
		addition, students taking the optional writing test receive a writing 
		score ranging from 2 to 12 (this is a change from the previous 1–36 
		score range); the writing score does not affect the composite score. The 
		ACT has eliminated the combined English/writing score and has added two 
		new combined scores: ELA (an average of the English, Reading, and 
		Writing scores) and STEM (an average of the Math and Science scores). 
		These changes for the writing, ELA, and STEM scores were effective 
		starting with the September 2015 test. 
		 
		Each question answered correctly is worth one raw point, and there is no 
		penalty for marking incorrect answers on the multiple-choice parts of 
		the test; a student can answer all questions without a decrease in their 
		score due to incorrect answers. This is parallel to several AP Tests 
		eliminating the penalties for incorrect answers. To improve the result, 
		students can retake the test: 55% of students who retake the ACT improve 
		their scores, 22% score the same, and 23% see their scores decrease
