I've found that while Excel can do basic IC50 calculations, it's really not the ideal tool for this. The methods others mentioned work, but they're pretty manual and prone to error if you're not careful with the formulas.If you're doing this regularly, consider using:- GraphPad Prism (specifically designed for bioassays)- ** specialized online calculators- R or Python** with appropriate packagesThat said, if you're stuck with Excel, the sigmoidal curve fit method is your best bet. Just be aware that Excel's curve fitting isn't as robust as dedicated statistical software, so your results might have wider confidence intervals. Always run replicates and calculate your error margins!

As a course instructor who uses Moodle regularly, I need to clarify something important right up front: downloading quiz questions from Moodle typically requires instructor-level permissions. Students generally can't export quiz questions due to academic integrity concerns.If you are an instructor, here's how:1. Log into your Moodle course as a teacher/manager2. Navigate to your quiz and click on it3. Click the "Edit quiz" button4. In the gear menu (top right), look for "Export" or "More" options5. Choose export format - Moodle supports various formats like GIFT, XML, or AikenThe GIFT format is particularly useful because it's plain text and can be imported back into Moodle later. Just be aware that some question types (like drag-and-drop) don't export perfectly in all formats.If you're a student wanting to study, your best bet is to use Moodle's built-in review features or ask your instructor if they can provide a practice quiz.

As a current KNUST student, I use the AIM app daily! Here's how to get logged in:1. Download the app from the App Store - search for "KNUST AIM" or "KNUST Academic Information Management"2. Open the app and you'll see login fields for Username and Password3. Your username is typically your student ID number (the one starting with... well, whatever format KNUST gave you)4. Your password is usually your index number initially, but you might have changed it during registrationCommon issues I've seen:- If it's your first time, try your index number as both username and password- Make sure you're connected to WiFi or have good data connection- The app sometimes acts up during peak registration periodsIf you're still having trouble, the KNUST IT support is actually pretty responsive. You can visit the IT directorate near the main administration block, or check their official support portal for specific login troubleshooting guides.Once you're in, the app is super useful for checking results, course registration, and even paying fees!

I'm currently training as a pharmacy tech through CVS's paid training program, so I can share the retail perspective!Retail Training Path:- Many chain pharmacies (CVS, Walgreens, etc.) offer paid training programs- They typically last 3-6 months while you work- They cover everything from pharmacy law to medication names- The company usually pays for your certification examWhat you'll learn:- Pharmacy terminology and drug classifications- Insurance billing and prescription processing- Inventory management- Customer service skillsThe retail route is great because you earn while you learn, but be prepared - it's fast-paced and you're dealing with customers from day one. The training is solid though, and having a major company on your resume opens doors later.If you go this route, make sure the program is recognized in your state and will qualify you to sit for the national certification exams.
