Weird looking stuff, why is it hard to snort? It seems like you could just cut it up with a razor.
Smoking speed is quite addictive and rushy, it might not be the best method for using it if you're still planning on using it to study. I'd recomend plugging it. The dose is 1/4-1/5 of the dose you'd use orally, it's less bad for you then smoking and less unpleasent then snorting (I hate snorting, it hurts and clogs up my nose, I only do it when I have to). Also plugged amphetamine is more enjoyable then any other method except perhaps the initial rush from smoked or IV in my opinion. All in all I think the high from rectal speed is better then the high from smoked or shot because there's less of a crash, it lasts longer and it doesn neccesarily make you (me in this case) redose over and over. But that's really a matter of opinion.
To plug it you just get a syringe without a needle (can be bought at most any pharmacy, sometimes they're even free). I use a 1 cc syringe because they're small and hold enough liquid for most drugs, they look like this-

You can also use a dropper like this, they hold more liquid and some people prefer how they feel, it's all a matter of preference really-

Then you just prep up a solution with water as if you were going to inject it, suck it into the rig (no need to filter), rub some canola oil or lube on the rig if you need to and plug away (there are guides on how to do it on here).
That's how I'd do it. It lasts for about 5 hours, comes up within 30 minutes usually and I find that it has a better feel then other methods. The problem with smoking is you often just smoke and smoke and smoke, so it'd be hard to study (for me at least) using this method because I'd always be either rushing from my last hit or going back to the pipe for my next one.
If you do decide on smoking it, there's a few ways to go about it. The "traditional" way to smoke speed is using a home made lightbulb vaporizer or a meth pipe. Meth pipes can be bought at most headshops (at least where I live), they look like this-

The headshops where I live sell them as "eucalyptus vaporizers", so that's what you should ask for if buying one. They're cheap too.
Lightbulb vaporizers have to be made, there's a lot of instructions on how to do so available online. The one thing to make sure of is that the bulb is completly clear before you use it. Once you cut the top off you should put salt inside and shake the salt around really well, this should remove most of the opaque stuff in there. Then you throw the salt away and I used to always follow that up with a soap and water wash followed by a straight water rinse.
An appropriate dose is hard to say because your product is impure. If the amphetamine was 100% pure then a good smoked dose to start at would be 5-15 mg. I'm not sure about the BA of amphetamine, but meth is as follows- 62.7% orally, 79% nasally, 99% rectally and 100%IV (of course).
Another thing- oral amphetamine is quite fun and much better then smoked amphetamine for purposes of studying. Smoked speed gives a very strong rush that quickly subsides, leaving a big blank space in the high (which is generally why it makes you use over and over, to get the rush to last the whole night). Oral Amphetamine is less rushy but a much smoother, long lasting high. Ultimatly though I think your best bet is plugging it. Maybe 15 mg to start, then wait for an hour and 15 minutes and see if you could use more and then do a booster of 5 or 10 mg. If it was pure I'd say just plug 7 mg and you'll be good for studying, but it's very hard to determine the proper dosage of street drugs.
