## Preface

Although I did managed to get 1500 on October test date as a non-native speaker, I would like to clear that I am far from an expert or a perfect test taker. In this article, I will provide self study guides for each section, valuable resources, and a few test day tips.

## Study Path

Throughout understanding:

• EC2 (AZ, auto-scaling, load balancer, security group)
• VPC (subnet, NAT gateway, BastionHost, Network ACL)
• S3 (different S3 classes, encryption, versioning, cross-region replication, lifecycle)
• RDS (multi-AZ, cross-region replication)

## Study Notes: Past SAT Curves

#### Don’t be afraid of the curve.

Literally, there is no SAT curve, which means SAT scores will never be affected by how other test takers perform on the test. The term ‘curve’ used in the SAT communities refers to ‘equating process’, which is used by the College Board to address for variations in difficulty among different test dates.

## Relative Clauses

Relative clauses are the phrases which start with a relative pronoun. While they probably essential to the meaning of a sentence, they are never crucial to the completeness of a sentence. For instance:

The tiger [that was hungry] ate my aunt earlier today.

Comma phrases are the additional phrases which are set off by a pair of commas. Take the following sentence:

A crucial part of doing well on the SAT Writing section is knowing how to strip away all these secondary phrases to get back to the essence of the sentence.

## Heat and Thermodynamics

Temperature scales: $\small T(K)=T(^{\circ}C)+273$

Temperature change: $\small Q=mc \Delta T$ (c is the specific heat.)

Phase change: $\small Q=mL$ (L is the latent heat of transformation.)

#### Thermal expansion

$\small \Delta L = \alpha L_{0} \Delta T$ ($\small \alpha$ is the coefficient of linear expansion.)

$\small \Delta V = \beta V_{0} \Delta T$ ($\small \beta$ is the coefficient of volume expansion.)
