Cram features and specs

  • User-Friendly Interface
    Cram features a straightforward and intuitive interface that makes it easy for users of all ages to create and study flashcards.
  • Large Database
    Cram boasts an extensive library of pre-made flashcards across various subjects, allowing users to easily find study materials on diverse topics.
  • Mobile Accessibility
    The platform offers mobile apps for both iOS and Android, enabling users to study on the go, anytime and anywhere.

    Users can create and personalize their own flashcards, including adding images and formatting text to enhance their study experience.
  • Study Modes
    Cram provides different study modes, such as memorization and testing, to cater to various learning styles and improve retention.

Possible disadvantages of Cram

  • Limited Free Features
    Many advanced features and functionalities are locked behind a paywall, which can restrict the usefulness of the platform for free users.
  • Ads for Free Users
    Free users are subjected to advertisements, which can be distracting and disrupt the flow of studying.
  • No Offline Access
    Users need an internet connection to access Cram's features and flashcards, limiting its usability in areas with poor connectivity.
  • Potential Quality Variability
    Since users can create their own flashcards, the quality and accuracy of content can vary widely, which might affect the reliability of study materials.
  • Data Privacy Concerns
    As with any online platform, there could be concerns regarding data privacy and how user information is stored and used.

PostgreSQL Exercises features and specs

  • Free and accessible
    PostgreSQL Exercises is completely free to use with no registration required, making it highly accessible to anyone who wants to practice SQL skills without any financial barrier.
  • Interactive practice environment
    The site provides a built-in SQL query editor where users can write and execute queries directly in the browser against a real database, getting immediate feedback on their results.
  • Progressive difficulty
    Exercises are well-organized into categories (basic, joins, aggregation, date, string, recursive) and progress from simple to complex, allowing learners to build their skills incrementally.
  • Realistic dataset
    The site uses a realistic country club management scenario with interconnected tables, giving learners practice with a coherent and relatable data model rather than abstract or disconnected examples.
  • Detailed solutions and explanations
    Each exercise comes with a detailed expected result set and a thorough explanation of the solution, helping learners understand not just what the answer is but why it works.

Possible disadvantages of PostgreSQL Exercises

  • Limited dataset scope
    The entire site relies on a single small dataset (a country club with members, facilities, and bookings), which limits exposure to diverse data modeling patterns and real-world complexity.
  • No user progress tracking
    Since there is no account system or registration, the site does not track user progress, making it difficult for learners to pick up where they left off or monitor their improvement over time.
  • PostgreSQL-specific syntax
    The exercises focus specifically on PostgreSQL syntax and features, which may not directly translate to other database systems like MySQL, SQL Server, or Oracle, potentially limiting transferability of learned skills.
  • Outdated design and interface
    The website has a dated visual design and user interface that lacks modern UX features such as syntax highlighting, auto-completion, or responsive mobile support, making it less pleasant to use compared to newer platforms.
  • Limited number of exercises
    The total number of exercises is relatively small compared to other competitive programming or SQL practice platforms, meaning advanced users may quickly exhaust the available problems.

  • Issue in remembering what services do in questions
    This is what I did....lots of flash cards. I used cram.com, but most sites work. I strongly suggest making your own, though. Don't put everything on them, just put the things you're struggling with. It's way more efficient to just work on the areas you don't know than to spend ages reviewing facts you already know. Source: about 3 years ago
  • What helped you pass Solutions Architect?
    I used Cantrill's course, TutorialDojo's practice exams, and cram.com for flash cards. I used the practice exams to help me identify where I was weak, and I'd go back and study those topics in more depth. Also, whenever I got a practice question wrong (or right only out of luck), I made up flash cards with whatever bits of information I was missing that would have helped me *know* what the right answer was. ...

    I don't use Anki but I used to make my own flash cards when I first started using cram.com lol. Source: about 4 years ago
  • Failed CHMM
    I made a set of flash cards at cram.com. These are from 2017 though, so I'm not sure if they're still applicable or if the test covers significantly different material now. Source: over 4 years ago
