When to pay for resources

• You’ve used free tools and you’re plateaued
• You need more practice questions than the free pool
• You need structured accountability you can’t self-impose
• You’re aiming for 1500+

What to avoid

• YouTube “guaranteed 1500” hype videos
• Old SAT prep books (pre-2024 — wrong Digital SAT format)
• Generic SAT word lists — Digital SAT doesn’t test vocab the old way
• $500+ courses before trying free resources
