ACT

This is an important information that you must consider noting down to avoid any trouble during registration and on your ACT exam day. 

Upon registration, the students are provided with the "test rosters". On the exam day, the examiner checks your "first" and "last" name on the test roster with the valid and acceptable ID you bring to the ACT test centre. If any discrepancy is recorded in both these documents, you won't be allowed to take the test. 

So, here are some acceptable name registration formats as described by ACT:

In short, you must retain both your first and last name while registering for the ACT exam. 

Yes, ACT exam is generally considered difficult. Here are the reasons for the same:

• ACT tests American English usage and conventions differ from the British English commonly taught in India. Hence, it becomes really difficult for students to follow the same pronunciation and colloquial terms as in the USA. 
• The passages in the Reading section of the ACT test contain references to the US culture, which might not be familiar to Indian students.
• The Science section in the ACT test focuses on data interpretation and graph analysis, rather than pure scientific concepts. This contradicts with the Indian system in where the stress is more on learning scientific concepts rather than data interpretation and graph analysis.
• ACT test offers very little time to perform on each section, which can be challenging for Indian students, especially if English isn't their first language. 

A composite score of 36, the highest possible score on the ACT exam, is equivalent to a perfect score. Each of the four ACT sections—English, Math, Reading, and Science—has a score between 1 and 36. The average of these four sector scores, rounded to the closest whole number, is the composite score. Less than 1% of test-takers receive a score of 36, which is a rare and distinguished achievement that indicates a high level of proficiency across all assessed subjects. Because it demonstrates high academic ability, critical thinking skills, and readiness for college-level work, a flawless ACT score can greatly boost a student's college application and get the attention of elite universities.

You can retake the ACT as many times as you'd like because there is no official cap on how many times you can take it. You can sign up for any or all of the seven occasions that the ACT is administered in the United States. The expense and time required for testing and preparation must be considered, though. You can raise your score by taking the ACT more than once, particularly if you use each opportunity to pinpoint and strengthen your areas of weakness. Since scores tend to rise with practice and familiarity, most students take the ACT two or three times. While some colleges permit "superscoring," which combines your the greatest section scores, others may view all of your scores.
