  How Our Online Test Prep Works

Sample TACHS Lesson

Interactive Lessons

Our lessons are comprised of short, bite-sized videos that are easy to follow. During a lesson, one or more questions follow each video to keep students engaged and help them retain what they just learned.

Students are able to pause and rewind the videos to make sure they fully understand before moving on.

If a student needs to refer back to a previous lesson, they can. The lessons will always be available, even after they are completed.

Personalized Feedback

While working through questions in the course, in lessons, and in practice tests, our platform tracks students’ performance.

We have broken down the topics on the TACHS into very specific topics that align with our lessons. This way students can pinpoint their strengths and weaknesses.

Not only do we let students know their proficiency in each topic, but we also show how much room there is to improve so students can use their time more wisely.

TACHS for Admission to Catholic High Schools

Many high schools in NYC use the TACHS as part of the admissions and scholarship criteria. In most cases, the TACHS is not used as the sole factor to determine admission into a school, but a higher test score improves chances of being accepted, can determine academic placement in the school, and can improve the likelihood of receiving a scholarship.
