GED Classes Ontario California

This post lists all available GED prep locations and testing sites in the Ontario region. California uses the fully computer-formatted GED exam for the state’s High School Equivalency (HSE) testing program.

Additionally, the state welcomed the HiSET exam for this purpose. The GED and HiSET may be taken online or at a state-approved HSE testing site. Learn more below.

Both exams assess knowledge at a level similar to that of graduating high school students.

The GED exam comes with four individual subtests in

• Math
• Science
• Social Studies
• English Language

These sub-exams may be written one (or more) at a time and in any order.

Achieve your educational goals with our free support. We offer free GED classes online for adults and free practice tests.

If online learning works for you, go on with Onsego GED Prep, a full-scope, accredited GED prep course, to get your GED fast. If online learning is not for you, contact a prep site near you for teacher-led instruction.

The HiSET has five subtests because the literacy part has two separate tests in reading and writing. These tests can be taken separately as well.

GED and HiSET Online

Both the GED and HiSET exams are now available online as well. In the past, online GED or HiSET testing was no option. Your personal appearance at an official, state-designated testing center was required. That has changed, though.

Now, the HiSET and GED exams can also be taken in an online, proctored format. A proctor will guide you and see if everything happens in accordance with the rules. To learn more, visit the online proctored HiSET test, and for the GED, check out the online proctored GED test.

The Four GED Tests

A few years ago, the GED exam was completely rebuilt to ensure it would remain a credible way of measuring applicants’ knowledge compared to that of graduating high schoolers.

The test has totally implemented what businesses and universities are expecting from GED graduates. The four sub-exams are timed tests:

• Language Arts: 155 minutes (including a small break)
• Math: 120 minutes
• Science: 90 minutes
• Social Studies: 70 minutes
