Problem: Article: Many teachers make their expectations clear at the beginning of the semester. Learning these quickly and adhering to them will give the teacher fewer reasons to pick on you.   Keep a copy of the syllabus with you during class as a reference. Be sure to follow any special formatting rules they may have for homework assignments. Teachers want students to listen to their lessons. Looking interested and engaged shows them that you take your learning seriously.  Sit up straight at your desk. Look up from your notebook to show you are paying attention. Make sure you are setting aside enough time to prepare for exams in the teacher's class. Maintaining a good grade in the class will show the teacher you are invested. Make sure you are raising your hand and answering questions a couple of times per class to show you are interested. Don’t over do it. Some teachers can be just as put off by the teacher's pet as they can a slacker student.
Summary: Learn the classroom rules and expectations. Look attentive. Study for quizzes and tests. Participate a moderate amount.

Problem: Article: Most of these tools include everything you need to find and replace the bad bulb: a continuity detector, piezoelectric sparker (shunt repairer), and light bulb removal tool. It costs roughly $20 US, so this may not be worth it if you only have a couple strings of lights. If you prefer to avoid buying such a specialized device, try the following alternatives:  Get a non contact voltage detector and skip down to tracing the dead bulb. Alternatively, buy a cheaper light bulb tester without the other features. Tackle the project hands-on with a homemade tool. Christmas lights are connected in series, meaning the whole string will go dark when one bulb fails. A failsafe called a shunt in each bulb is supposed to prevent this by closing the gap across the burnt-out bulb, but these often don't work properly. (In regions on 230V mains rather than 110V, the shunt usually does its job.) The sparker function on your repair tool will zap the shunt, hopefully succeeding in closing the gap:  Plug the string of lights into the socket on the repair tool. Press the button (or pull the trigger, depending on the model) about 20 times. You should hear a click each time. Plug the string of lights into a normal outlet. If the string is still dark, continue to the next step. If the string lights up except for one or two bulbs, skip down to replacing individual bulbs. If the string of lights still won't light up, move on to the detector. This detects the current running through the wires, so you can identify the point where it fails. Here's how:  Tug apart the braided wires to identify the one directly connected to the light bulbs. Place the detector on this wire about halfway along the string, between two bulbs. (If your tool has a small hole for a detector, place a light bulb into the hole instead.) If the tool hums or lights up (depending on model), the problem is in the half of the string farthest from the plug. If there is no hum or light, the problem is in the half closest to the plug. Move the tool to the middle of the problem area and test again, narrowing it down to ¼ of the string. Repeat until you find a bulb with current on one side of it and no current on the other. Mark this bulb with tape so you don't lose track, then replace this bulb as described below.
Summary: Buy a christmas light repair tool. Use the spark function on your repair tool. Trace the location of the dead bulb.

Problem: Article: If the door is locked with a bolt in addition to a lock in the door knob, you are going to be out of luck, at least when it comes to using a knife to get it open. However, you should be able to open a typical lock if it uses a spring-loaded latch system or has a button lock.  In a spring-loaded system, the latch springs out from a latch pocket that is built into the door jamb and keeps the door shut. But if you turn the knob or handle, you should be able to retract the latch. That is, unless it’s locked. To unlock this kind of a door, you should be able to take a butter knife or putty knife and manipulate the latch enough to retract it and open the door. The simplest lock to open, though, is the kind with the push button as the locking mechanism. All you will need to do with such a lock is to manipulate the inside of the lock enough to pop the button back out. You may not want to use a very sharp knife or a knife with a very sharp tip to open a door lock. One slip and you could injure yourself with the knife.  A simple butter knife or putty knife might work, so considering using that first.  A thin knife with a sharp point may be necessary depending on the size of the keyhole, though. You could use a pocket knife if the lock is very small, such as a bike lock.   If  the hole in the outside handle is a small circle instead of a slit, you could choose a paperclip or hair clip instead of a knife as it’s safer. If there is a slit on the outside handle, though, a knife should work.
Summary: Determine the type of lock, and understand how it works. Obtain a knife to open the door.

Problem: Article: If you receive an offer, make sure to respond as soon as possible. If you wait longer than 24 hours, you may lose a buyer. When you finally decide on an initial price for your domain, use charm pricing to help entice buyers. This is the act of knocking $1 off of the price to make it look more attractive (e.g. $499 vs. $500). If you have a domain that you know is worth a certain price, make sure you don't settle for less. Come armed with detailed information about the worth of your domain, and explain to the buyer why the price is what it is. When you are dealing directly with the buyer, make sure that any money that is transferred goes through an escrow service. This will ensure that all checks clear and that you aren't left with a bounced check and no domain. Escrow services may add a few days to a sale and cost you a percentage, but they can save you a lot of heartache. If your domains are selling for smaller amounts, escrow services may not be cost-effective.
Summary:
Respond quickly. Use charm pricing. Negotiate your price. Use escrow services for direct sales.
