Hi back, I was focusing my attention on the 10.1 version, not the 7, I actually have now idea how it performs but again for the same price I would prefer the Nexus 7 or EVGA Tegra Note7, according to benchmarks there so much faster that's it's almost embarrassing that Samsung thought they could be competitive, better resolution, faster graphics etc. Anyway, The 10.1 version is slow, I'm not trolling as I use and enjoy Android tablets very much, when their good. I have since bought a Nexus 10 and I full heartedly recommend this tablet over the SGT3 10.1. It's the same price but you get another 1GB of RAM (which you need!), higher resolution screen and my favourite, no TouchWiz crap. The SGT3 10.1 only has 300mb of free memory for apps, come one, even a closed minded person as yourself must see that as a bad thing. So call me whatever you want, I'm just warning people to stay away from these tablet at all costs, Complete GARBAGE. If you want a Samsung tablet pay a little more and get one of the new pro's or notes because their mid level stuff is just not competitive in todays market. Going back to your 7" inch, were you high when you bought it, the specs for that thing have got to be the worst I have seen for a tablet that's being sold in 2014. Look below;

I can't fathom why you would want a Samsung Tab 3 7, I'm actually dumbfounded why you chose this model. It's like someone let you choose between a 2014 BMW M5 or a 2005 Honda Civic for the same price and you chose the Civic. There is no way you can convince me that you made a wise purchase. Did you even bother reading the reviews, there isn't one that didn't conclude with; mediocre performing tablet that was outdated the second it left the factory, bad value.
The conclusion of this forum is such, no the Samsung Tablet 3's are not recommended for school. The hardware is dated especially for the price that Samsung is charging. There are those who might own one of these devices in this forum who will disagree and have but please do yourself a favour and just read the reviews. If that doesn't sway your opinion then just go and play with one. I don't want you to end up with a machine that you will regret. Go for the Nexus series, their a good value and are much faster than Samsungs offerings. If a SD card is important to you, Kingston sells a wifi device called MobileLite that can connect a SD Card, Mini SD Card, USB Stick and an external harddrive via Wifi to your tablet. It's like a mini NAS, pretty cool for 50 bucks, you can also share your data and use it as the main connection for LAN party's. It's a also an emergency battery for your tablet or phone.
