I recently obtained my first Salesforce certification — Salesforce Certified Platform App Builder.
The main two resources I used and that I highly recommend are:
- Trailhead (trailhead.salesforce.com) — Great hands on training that you can complete on your own time. As an added bonus, Trailhead training is FREE!
- “Salesforce Platform App Builder Developer 401” video training by Mike Wheeler — 20 hours of on demand video training that is easy to follow and effectively covers all the topics on the exam.
