Exam

Yes, it might be possible that SAT score is released on a public holiday. SAT scores are usually released before the weekend begins, that is, usually on a Friday. If SAT score release is delayed it may be possible that they are towards the weekend date (which usually doesn't happen). 

College Board usually declares the date of SAT exam result. The result usually comes in 2-4 weeks time. On the stipulated date of SAT score release, applicants can log on to their College Board account by 08:00 p.m. IST and access their results. Thus, applicants should check their accounts on their designated date of score release and not before that. This is the only intimation that applicants can get through the website of College Board.

There are just two sections on the Digital SAT exam and they are as follows:

1. Reading and Writing section
2. Math section

Bith sections have two sub sections. There are 54 questions tested on Reading and Writing, while there are just 44 questions on Maths section.

There is no paper based format of the SAT exam. There is only one format that is in play at the moment and that is the digital format. On the Digital SAT, there are:

• Reading & Writing Section: 54 Questions (64 minutes)
• Math Section: 44 Questions (70 minutes)

The difference between Khan Academy's prep and digital SAT prep is that,

• Khan Academy not just provides mock tests, they also have teaching videos to aid applicants with SAT prep.
• Khan Academy is the official partner of College Board for SAT exam prep after it became digitalised.
• On the other hand, College Board just has practice papers in PDF formats that can be downloaded for practice. 
• College Board does not give any prep material.
• Also, only when applicants register for SAT, can they access Bluebook App where they can take mocks in the exact same format as they will on the exam day.
